(
	Vector **output_vpp,
	const Matrix *input_mp
);

DESCRIPTION

This routine averages the rows of a matrix putting the result into the vector pointed to by *output_vpp (length num_cols). Missing values, identified by being close to DBL_MISSING are ignored. If all values for a colum are missing then the average is 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.
