Class R1toMatrix

java.lang.Object
  com.numericalmethod.suanshu.analysis.function.matrix.R1toMatrix

All Implemented Interfaces:

Function<Vector,Matrix>, RntoMatrix

Direct Known Subclasses:

R1toConstantMatrix

public abstract class R1toMatrix
extends java.lang.Object
implements RntoMatrix

This is a function that maps from R¹ to a Matrix space. It takes one real argument and outputs one matrix value. That is, /[ f(x) = A /]

R1toMatrix

public R1toMatrix()

Method Detail

dimensionOfDomain

public int dimensionOfDomain()

Description copied from interface: Function

Get the number of variables the function has. For example, for a univariate function, the domain dimension is 1; for a bivariate function, the domain dimension is 2.

Specified by:

dimensionOfDomain in interface Function<Vector,Matrix>

Returns:

the number of variables

dimensionOfRange

public int dimensionOfRange()

Description copied from interface: Function

Get the dimension of the range space of the function. For example, for a Rⁿ->R^m function, the dimension of the range is m.

Specified by:

dimensionOfRange in interface Function<Vector,Matrix>

Returns:

the dimension of the range

evaluate

public Matrix evaluate(Vector x)

Description copied from interface: Function

Evaluate the function f at x, where x is from the domain.

Specified by:

evaluate in interface Function<Vector,Matrix>

Parameters:

x - x

Returns:

f(x)

evaluate

public abstract Matrix evaluate(double x)

Evaluate f(x) = A.

Parameters:

x - x

Returns:

f(x)
