The error occurs as soon as there's an instance of an object of the class

undefined? And how can I add something to define missing symbols (something
that works with other compilers too)?
You have declared them. Have you implemented them anywhere?

Sure, in a file "DataAnalysis.cpp" added to the project...
That is your problem. When writing a class template like this, all of
the definitions need to be visible to any clients of the code. Put
your definitions in the DataAnalysis.h file.
Ok thx you very much. I didn't know this about class template... Now it
compiles in Release and Debug but running the program at a certain point
the debugger window is shown and the program is blocked... I I tried to
push "Continue" or "Step over" nothing changed except it appeared
"EXC_BAD_ACCES" at the bottom of the window...
