All Implemented Interfaces:

PostfixMathCommandI, Serializable

public class MatrixDictKeys
extends Keys

Implementation of Keys compatible with the matrix package. Allows

mat = [['x',2], ['y',3], ['z',4]];
keys(mat);

For all dictionary implementations the methods returns an VectorI.

Since:

4.1 extensions 2.2
