Modifier and Type	Method and Description
`Dimensions`	`calcDim(Dimensions ldim)` Find the dimensions of this operator when applied to arguments with given dimensions.

    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.

    Description copied from interface: UnaryOperatorI
    
    Find the dimensions of this operator when applied to arguments with given dimensions.

  - calcValue
```
public MatrixValueI calcValue(MatrixValueI res,
                              MatrixValueI lhs)
                       throws ParseException
```
    Description copied from interface: UnaryOperatorI
    
    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.
