Problem 2837. Modify subscripts

MATLAB supports object-oriented programming. Let's take an advantage of it in cody.

This problem starts here.

Let's take things a bit more seriously. There are subsasgn and subsref to overload:

>> A = sub_double([ 1 4 7
                    2 5 8
                    3 6 9]);
>> A([1 3],[3 1])

ans = 

    3x3 sub_double:

    double data:    
       7    3

>> A([1 2 3],[3 2 1]) = 0

A = 

    3x3 sub_double:

    double data:
       1     2     0
       4     0     6
       0     8     9

>> A(:)'

ans = 

    1x9 sub_double:

    double data:
       1     4     0     2     0     8     0     6     9

>> A(:,:)

ans = 

    1x3 sub_double:

    double data:
       1     0     9
