Placing breakpoint in subfunction

I wrote a simple program in Matlab with a main function and a subfunction. However, when I run the program, the subfunction doesn't seem to get recognized. For example, when I place a breakpoint to the left of where I defined "B" and click Run, I don't get the k>> prompt in the command window.

The code is as follows:

function test
global A;
A = 5;

function test2
B = 6;

For it to stop there, the first function, test, would have to call the second function test2(), which it currently does not do. It would if you did it like this:

function test
global A;
A = 5;
b_out = test2

function B = test2
B = 6;

Thanks for clearing that up. I have one more question. Why isn't the variable "A" recognized in the subfunction, even though I made it a global variable?

global variables aren't automatically global. They're only global to those functions that declare them global inside the function. If it's not in the function, it won't see it.

function B = test2
global A; % Now test2 can see A.
B = 6;

Mark the question as answered if we're done. Thanks.
