MATLAB Function Reference

orth - Range space of matrix

Syntax

B = orth(A)

Description

B = orth(A) returns an orthonormal basis for the range of A. The columns of B span the same space as the columns of A, and the columns of B are orthogonal, so that B'*B = eye(rank(A)). The number of columns of B is the rank of A.
