jit.dimop
Description
Applies an operator to elements within a subregion, across one or more dimensions, downsampling the input matrix in the process.
Discussion
For example, to downsample an incoming matrix to half the width and a quarter of the height, averaging all the values in each incoming 2 x 4 cell sub-region to a single output cell, use a step of 2 4, and an op of avg.
Matrix Operator
matrix inputs:1, matrix outputs:1
