Direct Known Subclasses:

MArrayAccess

public class ArrayAccess
extends VEle
implements LValueI

A postfix MathCommand which facilitates the getting and setting of vector and matrix elements. The class implements the set method of LValueI., read access is handled by parent VEle class. For examples a=[1,2,3]; a[2]=4; b=[[1,2],[3,4]]; b[2,1]=5;

Method Details

set

public void set(EvaluatorI pv,
 Node node,
 Object value)
         throws ParseException

Sets the LValue. For the equation a[2]=5

Specified by:

set in interface LValueI

Parameters:

pv - a pointer to the evaluator. The pv.eval() method can be used to evaluate the children of the node.

node - The top node for the LValue

value - the value obtained by evaluating the right hand side.

Throws:

ParseException
