public AdjLinearSolverQr_FDRM()

Method Details

setMaxSize

public void setMaxSize(int maxRows, int maxCols)

Description copied from class: LinearSolverQr_FDRM

Changes the size of the matrix it can solve for

Overrides:

setMaxSize in class LinearSolverQr_FDRM

Parameters:

maxRows - Maximum number of rows in the matrix it will decompose.

maxCols - Maximum number of columns in the matrix it will decompose.

getA

public org.ejml.data.FMatrixRMaj getA()

Compute the A matrix from the Q and R matrices.

Overrides:

getA in class LinearSolverAbstract_FDRM

Returns:

The A matrix.

addRowToA

public boolean addRowToA(float[] A_row, int rowIndex)

Description copied from interface: AdjustableLinearSolver_FDRM

Adds a row to A. This has the same effect as creating a new A and calling LinearSolver.setA(S).

Specified by:

addRowToA in interface AdjustableLinearSolver_FDRM

Parameters:

A_row - The row in A.

rowIndex - Where the row appears in A.

Returns:

if it succeeded or not.

removeRowFromA

public boolean removeRowFromA(int index)

Description copied from interface: AdjustableLinearSolver_FDRM

Removes a row from A. This has the same effect as creating a new A and calling LinearSolver.setA(S).

Specified by:

removeRowFromA in interface AdjustableLinearSolver_FDRM

Parameters:

index - which row is removed from A.

Returns:

If it succeeded or not.
