(
const Matrix *mp,
Vector **mean_vpp,
Vector **stdev_vpp
);
DESCRIPTION
This routine computes the means and stdev of the rows of a matrix and puts
the result into the vectors pointed to by *mean_vpp and *stdev_vpp
respetively.
If we are respecting missing values, then they are excluded from the average.
If all values for a colum are missing then the average is set to DBL_MISSING.
If either the maean or the standard deviation is not needed, then mean_vpp or
stdev_vpp can be NULL.
If *mean_vpp or *stdev_vpp are NULL, then a vector of the appropriate size is
created. If it is the wrong size, it is resized. Finally, if it is the right
size, then the storage is recycled, as is.
RETURNS
NO_ERROR on success, and ERROR on failure, with an error message being
set.
DISCLAIMER
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
