public java.lang.Double elementValue(java.lang.Object o)

Description copied from interface: MatrixFactoryI

Converts the argument to the type of elements of the matrix

Specified by:

elementValue in interface MatrixFactoryI

Returns:

the element value or null if it cannot be converted

identity

public MatrixI identity(int size)

Description copied from interface: MatrixFactoryI

Create an square identity matrix

Specified by:

identity in interface MatrixFactoryI

Parameters:

size - size

Returns:

a size by size identity matrix

identity

                        int cols)

Description copied from interface: MatrixFactoryI

Create an identity matrix.

Specified by:

identity in interface MatrixFactoryI

Returns:

a rows by cols identity matrix

zeroVec

public VectorI zeroVec(int size)

Description copied from interface: MatrixFactoryI

Create a vector with zeros

Specified by:

zeroVec in interface MatrixFactoryI

Returns:

a vector of zeros

zeroMat

public MatrixI zeroMat(int rows,

init in interface JepComponent

Parameters:

jep - the current Jep instance

getLightWeightInstance

public JepComponent getLightWeightInstance()

Description copied from interface: JepComponent

Gets a light-weight instance suitable for using in multiple threads.

Specified by:

getLightWeightInstance in interface JepComponent

Returns:

either an new instance, or 'this'.
