rankProfile() [5/5]

template<typename Mat>

M2_arrayintOrNull MatrixOps::rankProfile	(	const Mat &	A,
		bool	row_profile )

Returns either the row or column rank profile of A.

if row_profile is true, then row profile is computed, otherwise the column profile is computed.

The return value is an ascending sequence of non-negative integers with an entry a occurring iff the submatrix of A of the first (a-1) rows (resp columns) has lower rank than the submatrix of the first a rows (resp columns).

Notice that if the matrix is non-zero and the first row is non-zero, then the first entry will be 0.
