Constructor Detail

MatrixPartialDerivative

protected MatrixPartialDerivative(MatrixVariable var,
                                  String[] derivnames,
                                  Node deriv)

Protected constructor, should only be constructed through the findDerivative method in MatrixVariable.

Method Detail

getDimensions

public Dimensions getDimensions()

Description copied from interface: MatrixVariableI

The dimension of the variable.

Specified by:

getDimensions in interface MatrixVariableI

setDimensions

public void setDimensions(Dimensions dims)

Description copied from interface: MatrixVariableI

Sets the dimension of the variable. Will also allocate appropriate space for value container.

Specified by:

setDimensions in interface MatrixVariableI

getMValue

public MatrixValueI getMValue()

Description copied from interface: MatrixVariableI

Returns the value container of this variable. There is no setMValue as the value can be changed by setting the individual elements of value container.

Specified by:

getMValue in interface MatrixVariableI

setMValue

public void setMValue(MatrixValueI val)

Description copied from interface: MatrixVariableI

Sets the value of the variable (matrix aware).

Specified by:

setMValue in interface MatrixVariableI
