When convergent, it is continued analytically to the largest possible domain. The hypergeometric function depends on two vectors of parameters, called the numerator parameters :math:`a_p`, and the denominator parameters :math:`b_q`. It also has an argument :math:`z`. The series definition is .. math :: {}_pF_q\left(\begin{matrix} a_1, \dots, a_p \\ b_1, \dots, b_q \end{matrix} \middle| z \right) = \sum_{n=0}^\infty \frac{(a_1)_n \dots (a_p)_n}{(b_1)_n \dots (b_q)_n} \frac{z^n}{n!}, where :math:`(a)_n = (a)(a+1)\dots(a+n-1)` denotes the rising factorial. If one of the :math:`b_q` is a non-positive integer then the series is undefined unless one of the `a_p` is a larger (i.e. smaller in magnitude) non-positive integer. If none of the :math:`b_q` is a non-positive integer and one of the :math:`a_p` is a non-positive integer, then the series reduces to a polynomial. To simplify the following discussion, we assume that none of the :math:`a_p` or :math:`b_q` is a non-positive integer. For more details, see the references. The series converges for all :math:`z` if :math:`p \le q`, and thus defines an entire single-valued function in this case. If :math:`p = q+1` the series converges for :math:`|z| < 1`, and can be continued analytically into a half-plane. If :math:`p > q+1` the series is divergent for all :math:`z`. Note: The hypergeometric function constructor currently does *not* check if the parameters actually yield a well-defined function. Examples ======== The parameters :math:`a_p` and :math:`b_q` can be passed as arbitrary iterables, for example: >>> from sympy.functions import hyper >>> from sympy.abc import x, n, a >>> hyper((1, 2, 3), [3, 4], x) hyper((1, 2, 3), (3, 4), x) There is also pretty printing (it looks better using unicode): >>> from sympy import pprint >>> pprint(hyper((1, 2, 3), [3, 4], x), use_unicode=False) _ |_ /1, 2, 3 | \ | | | x| 3 2 \ 3, 4 | / The parameters must always be iterables, even if they are vectors of length one or zero: >>> hyper((1, ), [], x) hyper((1,), (), x) But of course they may be variables (but if they depend on x then you should not expect much implemented functionality): >>> hyper((n, a), (n**2,), x) hyper((n, a), (n**2,), x) The hypergeometric function generalizes many named special functions. The function hyperexpand() tries to express a hypergeometric function using named special functions. For example: >>> from sympy import hyperexpand >>> hyperexpand(hyper([], [], x)) exp(x) You can also use expand_func: >>> from sympy import expand_func >>> expand_func(x*hyper([1, 1], [2], -x)) log(x + 1) More examples: >>> from sympy import S >>> hyperexpand(hyper([], [S(1)/2], -x**2/4)) cos(x) >>> hyperexpand(x*hyper([S(1)/2, S(1)/2], [S(3)/2], x**2)) asin(x) We can also sometimes hyperexpand parametric functions: >>> from sympy.abc import a >>> hyperexpand(hyper([-a], [], x)) (-x + 1)**a See Also ======== sympy.simplify.hyperexpand sympy.functions.special.gamma_functions.gamma meijerg References ========== - Luke, Y.

It generalizes the hypergeometric functions. The Meijer G-function depends on four sets of parameters. There are "*numerator parameters*" :math:`a_1, \dots, a_n` and :math:`a_{n+1}, \dots, a_p`, and there are "*denominator parameters*" :math:`b_1, \dots, b_m` and :math:`b_{m+1}, \dots, b_q`. Confusingly, it is traditionally denoted as follows (note the position of `m`, `n`, `p`, `q`, and how they relate to the lengths of the four parameter vectors): .. math :: G_{p,q}^{m,n} \left(\begin{matrix}a_1, \dots, a_n & a_{n+1}, \dots, a_p \\ b_1, \dots, b_m & b_{m+1}, \dots, b_q \end{matrix} \middle| z \right). However, in sympy the four parameter vectors are always available separately (see examples), so that there is no need to keep track of the decorating sub- and super-scripts on the G symbol. The G function is defined as the following integral: .. math :: \frac{1}{2 \pi i} \int_L \frac{\prod_{j=1}^m \Gamma(b_j - s) \prod_{j=1}^n \Gamma(1 - a_j + s)}{\prod_{j=m+1}^q \Gamma(1- b_j +s) \prod_{j=n+1}^p \Gamma(a_j - s)} z^s \mathrm{d}s, where :math:`\Gamma(z)` is the gamma function. There are three possible contours which we will not describe in detail here (see the references). If the integral converges along more than one of them the definitions agree. The contours all separate the poles of :math:`\Gamma(1-a_j+s)` from the poles of :math:`\Gamma(b_k-s)`, so in particular the G function is undefined if :math:`a_j - b_k \in \mathbb{Z}_{>0}` for some :math:`j \le n` and :math:`k \le m`. The conditions under which one of the contours yields a convergent integral are complicated and we do not state them here, see the references. Note: Currently the Meijer G-function constructor does *not* check any convergence conditions. Examples ======== You can pass the parameters either as four separate vectors: >>> from sympy.functions import meijerg >>> from sympy.abc import x, a >>> from sympy.core.containers import Tuple >>> from sympy import pprint >>> pprint(meijerg((1, 2), (a, 4), (5,), [], x), use_unicode=False) __1, 2 /1, 2 a, 4 | \ /__ | | x| \_|4, 1 \ 5 | / or as two nested vectors: >>> pprint(meijerg([(1, 2), (3, 4)], ([5], Tuple()), x), use_unicode=False) __1, 2 /1, 2 3, 4 | \ /__ | | x| \_|4, 1 \ 5 | / As with the hypergeometric function, the parameters may be passed as arbitrary iterables. Vectors of length zero and one also have to be passed as iterables. The parameters need not be constants, but if they depend on the argument then not much implemented functionality should be expected. All the subvectors of parameters are available: >>> from sympy import pprint >>> g = meijerg([1], [2], [3], [4], x) >>> pprint(g, use_unicode=False) __1, 1 /1 2 | \ /__ | | x| \_|2, 2 \3 4 | / >>> g.an (1,) >>> g.ap (1, 2) >>> g.aother (2,) >>> g.bm (3,) >>> g.bq (3, 4) >>> g.bother (4,) The Meijer G-function generalizes the hypergeometric functions. In some cases it can be expressed in terms of hypergeometric functions, using Slater's theorem. For example: >>> from sympy import hyperexpand >>> from sympy.abc import a, b, c >>> hyperexpand(meijerg([a], [], [c], [b], x), allow_hyper=True) x**c*gamma(-a + c + 1)*hyper((-a + c + 1,), (-b + c + 1,), -x)/gamma(-b + c + 1) Thus the Meijer G-function also subsumes many named functions as special cases. You can use expand_func or hyperexpand to (try to) rewrite a Meijer G-function in terms of named special functions. For example: >>> from sympy import expand_func, S >>> expand_func(meijerg([[],[]], [[0],[]], -x)) exp(x) >>> hyperexpand(meijerg([[],[]], [[S(1)/2],[0]], (x/2)**2)) sin(x)/sqrt(pi) See Also ======== hyper sympy.simplify.hyperexpand References ========== - Luke, Y.

Syntax: python category.py action [-option] where action can be one of these: * add - mass-add a category to a list of pages * remove - remove category tag from all pages in a category * move - move all pages in a category to another category * tidy - tidy up a category by moving its articles into subcategories * tree - show a tree of subcategories of a given category * listify - make a list of all of the articles that are in a category and option can be one of these: Options for "add" action: * -person - sort persons by their last name * -create - If a page doesn't exist, do not skip it, create it instead If action is "add", the following options are supported: &params; Options for "listify" action: * -overwrite - This overwrites the current page with the list even if something is already there. * -showimages - This displays images rather than linking them in the list. * -talkpages - This outputs the links to talk pages of the pages to be listified in addition to the pages themselves. Options for "remove" action: * -nodelsum - This specifies not to use the custom edit summary as the deletion reason. Instead, it uses the default deletion reason for the language, which is "Category was disbanded" in English. Options for several actions: * -rebuild - reset the database * -from: - The category to move from (for the move option) Also, the category to remove from in the remove option Also, the category to make a list of in the listify option * -to: - The category to move to (for the move option) - Also, the name of the list to make in the listify option NOTE: If the category names have spaces in them you may need to use a special syntax in your shell so that the names aren't treated as separate parameters. For instance, in BASH, use single quotes, e.g. -from:'Polar bears' * -batch - Don't prompt to delete emptied categories (do it automatically). * -summary: - Pick a custom edit summary for the bot. * -inplace - Use this flag to change categories in place rather than rearranging them. * -recurse - Recurse through all subcategories of categories. * -pagesonly - While removing pages from a category, keep the subpage links and do not remove them * -match - Only work on pages whose titles match the given regex (for move and remove actions). For the actions tidy and tree, the bot will store the category structure locally in category.dump. This saves time and server load, but if it uses these data later, they may be outdated; use the -rebuild parameter in this case. For example, to create a new category from a list of persons, type: python category.py add -person and follow the on-screen instructions. Or to do it all from the command-line, use the following syntax: python category.py move -from:US -to:'United States' This will move all pages in the category US to the category United States.

""" Created on 1 Oct 2016 @author: Bruno Beloff (bruno.beloff@southcoastscience.com) DESCRIPTION The pt1000_calib utility is used to determine and save the voltage offset for each Pt1000 sensor. The utility operates by measuring the temperature using a Sensirion SHT sensor, measuring the voltage output of the Pt1000 sensor, and back-calculating the voltage offset. For the utility to operate, the I2C address of the Pt1000 ADC must be set. This is done using the dfe_conf utility. Note that the scs_analysis/gases_sampler process must be restarted for changes to take effect.
