R = rref(A)
R = rref(A, tol)
[R, p] = rref(A)
[R, p] = rref(A, tol)
| Parameter | Description |
|---|---|
| A | input matrix (double or single) |
| tol | tolerance: scalar or max(rows, cols) * eps(class(A)) * norm(A, inf) (default) |
| Parameter | Description |
|---|---|
| R | a matrix: reduced row echelon form of A. |
| p | a vector: nonzero pivot columns. |
R = rref(A) returns the reduced row echelon form of A.
[R, p] = rref(A) returns also the nonzero pivots p.
A = [magic(4), eye(4)]
