problem.getrows

Purpose
Returns the nonzeros in the constraint matrix for the rows in a given range.
Synopsis
problem.getrows(start, colind, colcoef, maxcoefs, first, last)
Arguments
start 
Array which will be filled with the indices indicating the starting offsets in the colind and colcoef arrays for each requested row. It must be of length at least last-first+2. Column i starts at position start[i] in the colind and colcoef arrays, and has start[i+1]-start[i] elements in it. May be None if not required.
colind 
Arrays which will be filled with at most maxcoefs column of the nonzero elements for each row. May be None if not required.
colcoef 
Array which will be filled with at most maxcoefs nonzero element values. May be None if not required.
maxcoefs 
Maximum number of elements to be retrieved.
first 
First row in the range.
last 
Last row in the range.
