Input Parameter#
svd - the singular value solver
Output Parameter#
scale - the scale parameter
Notes#
This parameter is relevant for the GSVD case only. If the parameter is positive, it indicates the scale factor for B in matrix Z=[A;B]. If negative, its absolute value is the threshold for automatic scaling.
