## org.lsmp.djep.jama
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.
`void` | `run(java.util.Stack s)` Throws an exception because this method should never be called under normal circumstances.

### Solve

    public Solve()

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`
