# NAME

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

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.
