GetRows Method (Int64[], Int32[], Double[], Int64, Int64, Int32, Int32)

Returns the nonzeros in the constraint matrix for the rows in a given range.

Namespace:   Optimizer
Assembly:  xprsdn (in xprsdn.dll) Version: 41.01.99
Syntax
C# 
public void GetRows(
	long[] start,
	int[] colind,
	double[] colcoef,
	long maxcoefs,
	out long p_ncoefs,
	int first,
	int last
)

Parameters

start
Type:  SystemInt64
Integer 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. Row i starts at position start[i] in the colind and colcoef arrays, and has start[i+1]-start[i] elements in it. May be null if not required.
colind
Type:  SystemInt32
Integer arrays of length maxcoefs which will be filled with the column indices of the nonzero elements for each row. May be null if not required.
colcoef
Type:  SystemDouble
Double array of length maxcoefs which will be filled with the nonzero element values. May be null if not required.
maxcoefs
Type:  SystemInt64
Maximum number of elements to be retrieved.
p_ncoefs
Type:  SystemInt64
Pointer to the integer where the number of nonzero elements in the selected rows will be returned. If the number of nonzero elements is greater than maxcoefs, then only maxcoefs elements will be returned. If p_ncoefs is smaller than maxcoefs, then only p_ncoefs will be returned.
first
Type:  SystemInt32
First row in the range.
last
Type:  SystemInt32
Last row in the range.
