NAME

get_rms_relative_col_error - Returns the RMS relative error of rows and/or entire matrices

SYNOPSIS

#include "m/m_mat_error.h"

Example compile flags (system dependent):
  -DLINUX_386 -DLINUX_386_P4  
   -I/home/kobus/include
   -L/home/kobus/load/linux_386_p4 -L/usr/local/lib -L/usr/lib
  -lKJB         -llapack -lblas -lg2c          -lXext -lX11 


int get_rms_relative_col_error
(
	Vector **result_vpp,
	const Matrix *first_mp,
	const Matrix *second_mp,
	double *error_ptr
);

DESCRIPTION

This routine calculates the RMS relative error of the columns of two dimension compatable matrices and/or the overall RMS relative error. If result_vpp is not NULL, then the RMS relative error of corresponding column are put into (*result_vpp) which is created or resized as needed. If error_ptr is not NULL, then the RMS relative error of the entire matrix is put into (*error_ptr). The relative error of corresponding pairs of number is computed by their difference normalized by their average.

RETURNS

NO_ERROR on success, and ERROR on failure (not very likely--currently impossible). Note that sending in matrices with incompatable dimensions is regarded as a bug. (See set_bug(3)).

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
