Property Value

Implements

A matrix is lower triangular if it is square and the entries on its super-diagonals are zero.

Let be a matrix, and consider its generic entry



where and are the number of rows and columns of , respectively.

If , then the matrix has super-diagonals: for , the -th super-diagonal is the collection of entries corresponding to the positions

Hence IsLowerTriangular returns true if and whenever .
