I'll explain my question with an example.
Lets say I have 26 folders in my working directory named A to Z, and each of these folders have 10 sub-folders with names 1 to 10.
Now, in a function I am preparing, I want to access files in a particular folder, which is defined by the input arguments when i call the function.
If I wanted to point to a file named xyz in folder 5 in folder A, doing it manually on command window would be /A/5/xyz
In my function, A and 5 are defined by the input argument. I tried converting the input argument A and 5 to strings str_fol1 and str_fol2 and point to /str_fol1/str_fol2/xyz and /'str_fol1'/'str_fol2'/xyz but it dint work.
Can anyone guide me, as to how to point to a file when the path to it is being defined by input arguments in a function?
Thanks

Use
full_filename = fullfile(str_fol1,str_fol2,filename);

%assuming:
%folder is a string with just the folder name, ex A
%file is a string with just the file name
file=[folder filesep subfolder filesep file]
%code to read the file, it depends on the file type and format
