scipy.special
|
||
=============
|
||
|
||
``scipy``\ ’s ``special`` module defines several functions that behave
|
||
as do the standard mathematical functions of the ``numpy``, i.e., they
|
||
can be called on any scalar, scalar-valued iterable (ranges, lists,
|
||
tuples containing numbers), and on ``ndarray``\ s without having to
|
||
change the call signature. In all cases the functions return a new
|
||
``ndarray`` of typecode ``float`` (since these functions usually
|
||
generate float values, anyway).
|
||
|
||
At present, ``ulab``\ ’s ``special`` module contains the following
|
||
functions:
|
||
|
||
``erf``, ``erfc``, ``gamma``, and ``gammaln``, and they can be called by
|
||
prepending them by ``scipy.special.``.

|

# code to be run in micropython

print(spy.special.erfc(b))
