	const Matrix *input_mp
);

DESCRIPTION

This routine sums the colums of a matrix putting the result into the vector pointed to by *output_vpp which will be a vector with length num_rows. If *output_vpp is 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. 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.

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.
