gecon

Usage: gecon(<matrix>,<scalar>)
Estimates the reciprocal of the condition number of a general matrix A, with the one-norm. Uses the LU factorization computed by GETRF. Currently MTL only handles column oriented matrices for this function.
Returns the reciprocal of the condition number.
Ex:gecon(A,5)
Uses the LAPACK function gecon See:http://www.osl.iu.edu/research/mtl/doc/geconcharconstLapackMatAconstRealReal.html
