Instance Property

scaling

User-supplied array for scaling.

Declaration

Discussion

This array can either be nil or a pointer to an array of real values with length greater than or equal to the size of the matrix being factored. The type of the array values is the element type of the matrix (but real, even if the matrix is complex).

If scalingMethod is SparseScalingUser, and this pointer is nil, no scaling is applied.

If scalingMethod is SparseScalingUser, and this pointer is non-nil, the user-provided array is used to scale the matrix before factorization.

If scalingMethod is not SparseScalingUser, the factor function computes its own scaling.

If this pointer is non-nil, the computed scaling is returned in the array.
