strictly upper triangular matrix


A strictly is an upper triangular matrixMathworldPlanetmath which has 0 on the main diagonal. Similarly a strictly lower triangular matrixMathworldPlanetmath is a lower triangular matrix which has 0 on the main diagonal. i.e.

[0a12a13a1n00a23a2n000a3n0000]

A strictly lower triangular matrix is of the form

[0000a21000a31a3200an1an2an30]
