scaling
An array that scales the matrix before factorization.
Declaration
var scaling: UnsafeMutableRawPointer?Discussion
This array can either be nil or a pointer to an array of real values with a length greater than or equal to the size of the matrix that you’re factoring. 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, the system doesn’t apply scaling.
If scalingMethod is SparseScalingUser, and this pointer isn’t nil, the system uses the user-provided array to scale the matrix before factorization.
If scalingMethod isn’t SparseScalingUser, the factor function computes its own scaling.
If this pointer isn’t nil, the computed scaling returns in the array.
