mm.math.left_matmul_at_modes¶
- math.left_matmul_at_modes(b_full, modes)¶
Left matrix multiplication of a partial matrix and a full matrix.
It assumes that that
a_partial
is a matrix operating on M modes and thatmodes
is a list ofM
integers, i.e., it will applya_partial
on the correspondingM
modes ofb_full
from the left.- Parameters:
