function

scipy.signal._filter_design:_align_nums

source: /scipy/signal/_filter_design.py :1807

Signature

def   _align_nums ( nums ,  xp )

Summary

Aligns the shapes of multiple numerators.

Extended Summary

Given an array of numerator coefficient arrays [[a_1, a_2,..., a_n],..., [b_1, b_2,..., b_m]], this function pads shorter numerator arrays with zero's so that all numerators have the same length. Such alignment is necessary for functions like 'tf2ss', which needs the alignment when dealing with SIMO transfer functions.

Parameters

nums: array_like

Numerator or list of numerators. Not necessarily with same length.

Returns

: nums: array

The numerator. If nums input was a list of numerators then a 2-D array with padded zeros for shorter numerators is returned. Otherwise returns np.asarray(nums).
