Member Function Documentation

int vnl_lsqr::aprod_ (  int *    mode, int *    m, int *    n, double *    x, double *    y, int *    leniw, int *    lenrw, int *    iw, double *    rw )  [static, protected]

void vnl_lsqr::diagnose_outcome (  vcl_ostream &    os )  const

Pontificate about the outcome of the last minimization.

int vnl_lsqr::get_number_of_iterations (    )  const [inline]

Definition at line 40 of file vnl_lsqr.h. References ls_, max_iter_, and num_iter_.

int vnl_lsqr::minimize (  vnl_vector< double > &    x )

Perform the minimization starting from x=0 and putting the result into x. Return code may be translated with translate_return_code().

void vnl_lsqr::set_max_iterations (  int    max_iter )  [inline]

Definition at line 33 of file vnl_lsqr.h. References num_iter_.
