rref
computes matrix row echelon form by lu transformations
Calling Sequence
R=rref(A)
Arguments
- A
m x n matrix with scalar entries
- R
m x n matrix,row echelon form of a
Description
rref
computes the row echelon form of the given matrix by left lu
decomposition. If ones need the transformation used just call
X=rref([A,eye(m,m)])
the row echelon form R
is X(:,1:n)
and
the left transformation L
is given by X(:,n+1:n+m)
such as L*A=R
Examples
A=[1 2;3 4;5 6]; X=rref([A,eye(3,3)]); R=X(:,1:2) L=X(:,3:5);L*A
