orth             Scilab Group             Scilab Function              orth
NAME
   orth - orthogonal basis
  
CALLING SEQUENCE
 Q=orth(A)
PARAMETERS
 A    : real or complex matrix
      
 Q    : real or complex matrix
      
DESCRIPTION
   returns Q, an orthogonal basis for the span of A. Range(Q) = Range(A) and
  Q'*Q=eye.
  
   The number of columns of Q is the rank of A as determined by the QR
  algorithm.
  
EXAMPLE
 A=rand(5,3)*rand(3,4);
 [X,dim]=rowcomp(A);X=X';
 svd([orth(A),X(:,1:dim)])
SEE ALSO
