Is there a facility in AmiBroker to calclate directly the Row Reduce Echelon Form for a general matrix.

MXSOLVE will deliver this result for matrices with rank equal to the number of rows (sometimes requiring some manipulation to identify an invertible sub-matrix). But, MXSOLVE appears to return Null in all cases where rank is less than the number of rows (at least that's how I'm reading the Help material).

The Row Reduced Echelon Form of a matrix of deficient rank can still be quite useful for certain applications, so I'm hoping that there's an AmiBroker tip on how to do this with built-in functions.

Thanks,

David
