pyyeti.ytools.mkpattvec

pyyeti.ytools.mkpattvec(start, stop, inc)

Make a pattern “vector”.

Parameters:

• start (scalar or array) – Starting value.

• stop (scalar) – Ending value for first element in start (exclusive).

• inc (scalar) – Increment for first element in start.

Returns:

pattvec (array) – Has one higher dimension than start. Shape = (-1, start.shape).

Notes

The first element of start, stop, and inc fully determine the number of increments that are generated. The other elements in start go along for the ride.

Examples

>>> from pyyeti import ytools
>>> import numpy as np
>>> ytools.mkpattvec([0, 1, 2], 24, 6).ravel()
array([ 0,  1,  2,  6,  7,  8, 12, 13, 14, 18, 19, 20])
>>> x = np.array([[10, 20, 30], [40, 50, 60]])
>>> ytools.mkpattvec(x, 15, 2)
array([[[10, 20, 30],
        [40, 50, 60]],

       [[12, 22, 32],
        [42, 52, 62]],

       [[14, 24, 34],
        [44, 54, 64]]])
