C# - Keep in memory variables between calling 2 different matlab routines

Is it possible to keep in memory variables used in a 1st matlab routine called by C#, when I call a 2nd matlab routine?
For example if I have in my C# application
matlabroutine1(); matlabroutine2();
and matlabroutine1 allocates a variable value1, when I call matlabroutine2 value1 is available?

This may be a situation in which using global variables would be appropriate.

What you are looking for is "setmcruserdata" and "getmcruserdata". Im assuming you are using the Builder NE. If so, also make sure that "matlabroutine1" and "matlabroutine2" are both methods in the same deployed C# class. These methods will share a common workspace in the MCR that will enable them to share data in the way you want.

You have the correct idea with the .m functions you wrote. I think the issue is in how you are calling it in C#:
Calcolo.dammiA(out b, varNm);
You declared "b" to be an int, all outputs from deployed MATLAB functions need to be some sort of "MWArray". It looks like you are trying to use an interface wrapper with "Class1". I would leave this out until you are comfortable working with MWArray's. I would expect that you will have to do something more like this:
MWArray[] mlout = Calcolo.dammiA(1, varNm); // "1" means you are only expecting one output.
int b = (int)(MWNumericArray)mlout[0] // Since you know the first(only) output is an integer
The documentation for Builder NE has many examples of how to work with MWArrays.
Good luck!
