Synopsis

     #include <bpipe/bpipe.h>
     
     
     
BPMatrix *bpipe_matrix_min( BPMatrix *a, BPMatrix *b );

Parameters

BPMatrix *a
Not Documented.
BPMatrix *b
Not Documented.

Description

This routine creates a binary pipe matrix which has the minimum number of dimensions and extent from a pair of binary pipe matrix argument. It allocates memory for the matrix structure and its associated data.
