PostfixMathCommandI, Serializable

public class MatrixDictSize
extends Size

Implementation of Size compatible with the matrix package. Allows

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

Default name for this function is "numElements" to prevent conflict with the size function for matricies.

Since:

4.1 extensions 2.2
