How can I pass two matrices as arguments in a matlab executable?

Question

For example in MatLab, command line I use:

functionname([1 2 3;4 5 6],[1 3 2;7 9 8])

I get a result. But, on windows using cmd:

functionname "[1 2 3;4 5 6]" "[1 3 2;7 9 8])

This doesn't seem to work.

What result are you expecting? Does this function output something to the console, or did you expect a return value to be magically printed? — paddy, Dec 19 '13 at 03:57
The function takes two matrices as arguments, make same calculations and return a result. I tested it directly on the matlab command line ,it works. But after creating the executable, I can't find how I can pass two matrices as arguments. — user3117667, Dec 19 '13 at 14:22

This question has been answered on How to create a executable .exe file from .m file.

You should use mcc -m yourfile and it's only work with Matlab installed machines. One other way could be using .dll and running it via Visual Studio.

I've already created the exe file, the problem is that I can't find how I can pass two matrices as arguments. For two numeric values for example i can use functionname 4 5 but functionname "[1 2 3;4 5 6]" "[1 3 2;7 9 8]) doesn't work – user3117667 Dec 19 '13 at 14:04

You have to cast the arguments to numerical on demand:

In functionname(a, b), add

if ischar(a)
  a = eval(a);
end

if ischar(b)
  b = eval(b);
end

Now functionname() can be called with numerical arguments and from the command line with string arguments:

functionname "[1 2 3;4 5 6]" "[1 3 2;7 9 8]"

Note that eval() does the opposite of mat2str().
