Numpy

Contents

These functions are meant to decorate generator functions to return numpy arrays. They are signature preserving decorators, and can therefore be used to decorate class methods as well as standalone functions.

np_c

This decorates generator functions and applys the numpy.c_ routine to the output. For example:

@pydecorator.np_c
def array():
    for col in [[1,2,3],[4,5,6],[7,8,9]]:
        yield col

>>> array()
[[1 4 7]
 [2 5 8]
 [3 6 9]]

np_r

This decorates generator functions and applys the numpy.r_ routine to the output. For example:

@pydecorator.np_r
def array():
    for row in [[1,2,3],[4,5,6],[7,8,9]]:
        yield row

>>> array()
[1 2 3 4 5 6 7 8 9]

np_rows

This decorates generator functions and returns their output as the rows of a numpy.array. For example:

@pydecorator.np_rows
def array():
    for row in [[1,2,3],[4,5,6],[7,8,9]]:
        yield row

>>> array()
[[1 2 3]
 [4 5 6]
 [7 8 9]]
