All Implemented Interfaces:

PostfixMathCommandI, Serializable

public class MatrixDictEntries
extends Entries

Implementation of Entries compatible with the matrix package. Allows

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

For all dictionary implementations the methods returns an MatrixI with two columns.

Since:

4.1 extensions 2.2
