assigning multiple varables with one call to single-output MATLAB function

Question

I want to take the simple example code and assign a unique rand() to each variable -- on one line:

X = rand();

Y = rand();

possible?

why wont you just use a vector ? `x=rand(1,2)` then `x(1)` and `x(2)` are your two variables... — bla, Sep 13 '13 at 23:33
agreed - that would be cleaner here. for the larger problem, i needed a lot of variables with unique descriptive names — j4ke, Sep 14 '13 at 03:12

If you absolutely want it in a single line, you can do:

[X, Y] = deal(rand(), rand());

Not a big gain, though.

cool, that's the function i was looking for - thanks! (agreed, it's overkill / loses readability for this light code, but will help a great deal for my other implementations.) – j4ke Sep 14 '13 at 03:09
@j4ke / Milo, In MATLAB version 7.0 or higher, you can achieve the same effect without `deal` using [comma-separated lists](http://www.mathworks.com/help/matlab/matlab_prog/comma-separated-lists.html). Refer to [this answer](http://stackoverflow.com/q/2337126/1336150#2337336) of the duplicate question I've linked to. – Eitan T Sep 15 '13 at 13:28

One line...

X = rand(); Y = rand();

... is that all you needed?
