MATLAB varying no of variable reading

[arve9066]

I have a mat file that contains variables named deterministically like a1_1,a1_2,a1_3.... a1_n.. n is variable depending on the mat file I read, but the naming convention remains the same. I need to read all of these in a loop that goes from 1 to n. What is the best way to achieve this?

If you just do "load filename" doesn't it bring in all those variables?

I mean once I load the file in to matlab, how to access those variables in a loop if I know 'n'.

Not sure you can do that. You could load them into an array and access them that way.

Ok.. Actually I am running another m file to create those mat files. Is there a different way I can save those variables to the mat files which will help me access these in the way I described earlier. My program does this - I have a varying number of input files which needs to be processed. Each file is processed by an m file to get a set of variables corresponding to that input file which I save in to a mat file. I do the same for all these input files and append the variables to the same mat file. Once I have all these files processed, I work with the mat file to further process the data.

use the variables and do not clear the memory, keep the variable name different in every mat file, and use the values in multiple mat files.
