C# 
public void SparseBTran(
	double[] val,
	int[] ind,
	out int p_ncoefs
)

Parameters

val
Type:  System.Double
Double array of length ROWS containing the values which are to be post-multiplied by the basis inverse. The transformed values are returned in this array.
ind
Type:  System.Int32
Integer array of indices identifying the non-zero entries of val. The indices of the non-zero entries of the transformed vector in val will be returned here. This array must be allocated to hold at least ROWS indices.
p_ncoefs
