Hi everyone,

I would like to ask you a anyone who knows about connection of .m matlab function in a windows form Application. In particular, I have created a windows application in Visual Studio 2010.At the same time i have created a matlab function,let's call this function "test.m".
My problem is how to call the above-mentioned function, test.m, in my window application.Is there any method for this call? My windows application consists of several windows and of course buttons.All i want is to press the button in question and call the test.m function.
How can i achieve that??If any code is required or something else please write in this topic and i will answer immediately.
