NAME
max_rel_matrix_difference - Returns the max relative difference between two matrices
SYNOPSIS
#include "m/m_mat_metric.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
double max_rel_matrix_difference
(
const Matrix *first_mp,
const Matrix *second_mp
);
DESCRIPTION
This routine calculates the maximum of
2 * | M(i,j) - N(i,j) | / |M(i,j)| + |N(i,j)|
for two dimension compatable matrices.
If 2 elements are zero, their relative difference is considered 0.
To support test program, if both matrices are NULL, the different is zero.
RETURNS
The distance between the two matrices, or a negative number if there is an
error (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.
