overload subsasgn

[erik-roberts]

permit direct assignment of obj.data using object with () or {}.
eg before

obj = MDD(magic(3));
obj.data
obj.data(1:3) = 1:3;
obj.data

eg after

obj = MDD(magic(3));
obj.data
obj(1:3) = 1:3;
obj.data

I'm not sure this is working the way it is intended. Commenting out the overloaded subsasgn in MDD.m still yields the following

obj = MDD(magic(3));
obj.data
obj.data(1:3) = 1:3;
obj.data
ans =
    8     1     6
    3     5     7
    4     9     2
ans =
    1     1     6
    2     5     7
    3     9     2

e.g. you can always write to data_pr as long as you don't change the dimensions.

Second, the overloaded subsasgn produces an error when you try to do other assignments. (Running tutorial_MDD.m, there is an error at line 141) :

Field assignment to a non-structure array object.
Error in MDD/subsasgn (line 928)
                obj.data_pr = builtin('subsasgn', obj.data, S, value);
Error in tutorial_MDD (line 141)
xp.meta = meta;
