Summary 0000024: FIXED: Inefficient BuildChebyshevLeastSquaresConstrained
Description Subroutine compexity must be O(N*M^2), but is O(N^2*M) which is much worse. Although it works correctly.

This additional overhead is due to incorrect parameters passed to SVD decomposition subroutine (we need only M singular vectors, but whole N*N matrix was requested).
