Please remember that everything we know about your particular problem comes from what you write in your question. At least for me, there is not enough explanation here for me to understand what you want to do.

The normal right answer is to just use arrays. This limits you to using normal indexing techniques (logical & positive integer)
MeasNr = 1;
Meas_(MeasNr) = 5;
The "other" right answer is to define a class that stores both index values & result values. This is more work, but allows you to have noninteger indexing
The wrong answer, is to dynamically change variable names. - This should only be used in dire circumstances:
eval(['Meas_' num2str(MeasNr) ' = 5;'])

Actually, the 'other' right answer is not particularly more work, it already exists as
containers.Map

I read this question as if you want to get variable names such as Meas_1, Meas_2 etc. That's not how you should work in Matlab. More information e.g. http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F
