template <class LapackMatA, class Real>
int gecon(char _norm, const LapackMatA& a, const Real& _anorm, Real& rcond) ;
| ||||||

Description
| ||||||

Estimate the reciprocal of the condition number of a general matrix
A, with either the one-norm or the infinity-norm. GECON uses the LU
factorization computed by GETRF. Currently MTL only handles column
oriented matrices for this function.
- norm (IN -
`char`) Specifies whether to do one-norm or infinity norm. One of the following is required: '1' the 1-norm condition number 'I' the infinity-norm condition number - a (IN - matrix(M,N)) The coefficient matrix A.
- anorm (IN - Real number) The one or infinity norm of matrix A, which is of the same numerical type as A.
- rcond (OUT - Real number) The estimated reciprocal condition of matrix A.
- info (OUT -
`int`) 0 : function completed normally < 0 : The ith argument, where i = abs(return value) had an illegal value.
