Class Solve

java.lang.Object
  org.nfunk.jep.function.PostfixMathCommand
      org.lsmp.djep.jama.Solve

All Implemented Interfaces:

BinaryOperatorI, PostfixMathCommandI

public class Solve
extends PostfixMathCommand
implements BinaryOperatorI

z = solve(x,y) solves x*z = y where x,y,z are real matricies. Serves a wrapper around the Jama linear algebra function.

Method Summary

Dimensions	calcDim(Dimensions ldim, Dimensions rdim) Find the dimensions of this operator when applied to arguments with given dimensions.
MatrixValueI	calcValue(MatrixValueI res, MatrixValueI lhs, MatrixValueI rhs) Calculates the value of this operator for given input with results stored in res.

Method Detail

run

public void run(java.util.Stack s)
         throws ParseException

Description copied from class: PostfixMathCommand

Throws an exception because this method should never be called under normal circumstances. Each function should use it's own run() method for evaluating the function. This includes popping off the parameters from the stack, and pushing the result back on the stack.

Specified by:

run in interface PostfixMathCommandI

Overrides:

run in class PostfixMathCommand

Throws:

ParseException

calcDim

public Dimensions calcDim(Dimensions ldim,
                          Dimensions rdim)

Description copied from interface: BinaryOperatorI

Find the dimensions of this operator when applied to arguments with given dimensions.

Specified by:

calcDim in interface BinaryOperatorI

calcValue

public MatrixValueI calcValue(MatrixValueI res,
                              MatrixValueI lhs,
                              MatrixValueI rhs)
                       throws ParseException

Description copied from interface: BinaryOperatorI

Calculates the value of this operator for given input with results stored in res. res is returned. Using this method is slightly faster than the standard run method as it eliminates the construction of tempoary objects.

Specified by:

calcValue in interface BinaryOperatorI

Throws:

ParseException
