How can I create a 2-term, 1-by-1 string using sprintf?

I am using the following code to refer to 4000x15 doubles I have in my workspace, they are named P1-17. When I use the code however, the name becomes a 1x2 char and therefore a variable itself. When I try to use it in the function that's in the loop, it does not refer to the 4000x15 data at all.
Does anyone know how to fix this or do it in another way? I have tried a lot of things but I can't figure this one out.
for j = 1:1:17
filename = (sprintf('%s%d','P',j)) ;
[sgmean] = DataPrep(filename) ;
end

"but use one of the alternatives in the documentation you attached?"
You don't need to guess, I already told you which alternative to use: LOAD into an output variable.

Here is a way to import those badly-named variables, assuming exactly one variable per MAT file:
N = 17;
C = cell(1,N);
for kk = 1:N
F = sprintf('P%d',kk);
C(kk) = struct2cell(load(F));
end
Your data are stored in the cell array C, for example the 2nd file:
C{2}
The code would be simpler and more robust if the variable names were exactly the same in every file.
