is it possible to substitute multiplication and division by addition and subtraction respectively in MATLAB?

is it possible to substitute multiplication and division by addition and subtraction respectively in MATLAB?

[Walter Roberson]

The quantities being manipulated, are they known to be positive?

Of course. Instead of typing:

x = 3*5;

type:

x = 3+5;

If that's not what you meant, explain in more detail what you want to do and we can suggest whether or not it's possible.

No, you are getting me wrong. e.g. x=3*5; so x=15 I would replace it with

x=3+3+3+3+3 so x=15

[Walter Roberson]

There is no automatic code for that purpose, not even for the symbolic toolbox.

[Steven Lord]

Sure.

x1 = 3*5;
x2 = 3+3+3+3+3;

Now I suspect doing this manual substitution is not what you have in mind or what you're being asked or told to do. Why don't you tell us the problem you're trying to solve and what constraints or requirements you have and we may be able to offer suggestions.

For example if this is a string manipulation question then it becomes a bit easier... provided that you do not have to deal with nested brackets.
