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

public void GetCols(
	long[] start,
	int[] rowind,
	double[] rowcoef,
	long maxcoefs,
	out long p_ncoefs,
	int first,
	int last
)

Parameters

start   Int64

Integer array which will be filled with the indices indicating the starting offsets in the rowind and rowcoef arrays for each requested column. It must be of length at least last-first+2. Column i starts at position start[i] in the rowind and rowcoef arrays, and has start[i+1]-start[i] elements in it. May be null if not required.

rowind   Int32

Integer array of length maxcoefs which will be filled with the row indices of the nonzero coefficents for each column. May be null if not required.

rowcoef   Double

Double array of length maxcoefs which will be filled with the nonzero coefficient values. May be null if not required.

maxcoefs   Int64

The size of the rowind and rowcoef arrays. This is the maximum number of nonzero coefficients that the Optimizer is allowed to return.

p_ncoefs   Int64

Pointer to an integer where the number of nonzero coefficients in the selected columns will be returned. If p_ncoefs exceeds maxcoefs, only the maxcoefs first nonzero coefficients will be returned. May be null if not required.

first   Int32

First column in the range.

last   Int32

Last column in the range.
