public RrefGaussJordanRowPivot_FDRM()

Method Details

setTolerance

public void setTolerance(float tol)

Description copied from interface: ReducedRowEchelonForm_F32

Specifies tolerance for determining if the system is singular and it should stop processing. A reasonable value is: tol = EPS/max(||tol||).

Specified by:

setTolerance in interface ReducedRowEchelonForm_F32<FMatrixRMaj>

Parameters:

tol - Tolerance for singular matrix. A reasonable value is: tol = EPS/max(||tol||). Or just set to zero.

reduce

public void reduce(FMatrixRMaj A,
 int coefficientColumns)

Description copied from interface: ReducedRowEchelonForm

Puts the augmented matrix into RREF. The coefficient matrix is stored in columns less than coefficientColumns.

Specified by:

reduce in interface ReducedRowEchelonForm<FMatrixRMaj>

Parameters:

A - Input: Augmented matrix. Output: RREF. Modified.

coefficientColumns - Number of coefficients in the system matrix.

swapRows

protected static void swapRows(FMatrixRMaj A,
 int rowA,
 int rowB)
