Standard_EXPORT | math_GaussLeastSquare (const math_Matrix &A, const Standard_Real MinPivot=1.0e-20) |
Given an input n X m matrix A with n >= m this constructor performs the LU decomposition with partial pivoting (interchange of rows) of the matrix AA = A.Transposed() * A; This LU decomposition is stored internally and may be used to do subsequent calculation. If the largest pivot found is less than MinPivot the matrix is considered as singular. . | |
Standard_Boolean | IsDone () const |
Returns true if the computations are successful, otherwise returns false.e . | |
Standard_EXPORT void | Solve (const math_Vector &B, math_Vector &X) const |
Given the input Vector this routine solves the set of linear equations A . X = B. Exception NotDone is raised if the decomposition of A was not done successfully. Exception DimensionError is raised if the range of B Inv is not equal to the rowrange of A. Exception DimensionError is raised if the range of X Inv is not equal to the colrange of A. . | |
Standard_EXPORT void | Dump (Standard_OStream &o) const |
Prints on the stream o information on the current state of the object. Is used to redefine the operator <<. . | |
