Hi,

I Have 51 files in their own directory all of .out extention created by a seperate program, all numbered 0 to 50.

out
out
out

and so on til 50.out.

I need to load each file 1 by one to do calculations upon them within a for loop. How would I do this using the count variable to load the file, if the directory is set beforehand?

i.e.

%set directiory
cd(......)
%for loop
For count = 0:50,
     data = count.out     *<-----this line* 
     .....

Many thanks!

You can use sprintf or num2str. num2str is easier to use, but sprintf gives many more options including leading zeros.

data = load([num2str(count),'.out']);
