	Vector **output_vpp,
	const Matrix *input_mp
);

DESCRIPTION

This routine averages the columss of a matrix putting the result into the vector pointed to by *output_vpp which becomes a vector of size num_rows. Negative values are ignored. If all values for a colum are negative then the average is negative (specially, DBL_MISSING). 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.

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.
