get_rms_col_error - Computes the RMS error of columns and/or whole matrix
Example compile flags (system dependent):
-DLINUX_X86_64 -DLINUX_X86_64_OPTERON -DGNU_COMPILER
-lKJB -lfftw3 -lgsl -lgslcblas -ljpeg -lSVM -lstdc++ -lpthread -lSLATEC -lg2c -lacml -lacml_mv -lblas -lg2c -lncursesw
const Matrix *first_mp,
const Matrix *second_mp,
This routine calculates the RMS error of the columns of two dimension
compatable matrices. Corresponding columns are treated as vectors. For each
such pair we calcluate the error which is the standard vector norm of their
difference. The RMS value of all such errors is put into *error_ptr. In
addition, if result_vpp is not NULL, then the error each componant of the
column are calculated and placed into the vector pointed to by *result_vpp.
The target vector *result_vpp is created or resized if requred.
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)).
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
