Method Detail

• addStandardFunctions

  public void addStandardFunctions()

  Description copied from class: JEP
  Adds the standard functions to the parser. If this function is not called before parsing an expression, functions such as sin() or cos() would produce an "Unrecognized function..." error. In most cases, this method should be called immediately after the JEP object is created.

  Overrides:

  addStandardFunctions in class JEP

• evaluate

  public Object evaluate(Node node)
                  throws ParseException

  Evaluate a node. If the result is a scaler it will be unwrapped, i.e. it will return a Double and not a Scaler.

  Overrides:

  evaluate in class JEP

  Parameters:

  node - the top node of the tree representing the expression.

  Returns:

  The value of the expression

  Throws:

  ParseException - if for some reason the expression could not be evaluated

• evaluateRaw

  public Object evaluateRaw(Node node)
                     throws Exception

  Evaluate a node. Does not unwrap scalers.

  Throws:

  Exception

• setElementMultiply

  public void setElementMultiply(boolean value)

  When set the multiplication of vectors and matrices will be element by element. Otherwise multiplication will be matrix multiplication (the default).
