How to write a for loop that converts one file type to another?

Hello all,

I have 34 files saved in my working directory folder of the type .edf, and I am using the function "edfread" to convert them to a type that is readible by matlab. I have no problem using the function to convert 1 file at a time, however, I would like to write a for loop to convert all of the 34 edf files at once.

The saved edf files are saved like this (each subject has 2 channes of data):

Subject0_1.edf

Subject0_2.edf

Subject1_1.edf

Subject1_2.edf

Subject2_1.edf

Subject2_2.edf

Subject3_1.edf

Subject3_2.edf

Subject4_1.edf

Subject4_2.edf

Subject5_1.edf

Subject5_2.edf

and so on....

My code to convert the edf file for a single subject looks like this:

[Hdr_Subj0_1,Sig_Subj0_1]= edfread('Subject0_1.edf');

[Hdr_Subj0_2,Sig_Subj0_2]= edfread('Subject0_2.edf');

( I don't want to copy and past these same 2 lines of code 34 times)

I know that I need to use %d someplace in my for loop, but I can't figure out exactly how to code it.

for i = 1:34

[Hdr_Subji_1,Sig_Subji_1]= edfread('Subject%d_1.edf');

[Hdr_Subji_2,Sig_Subji_2]= edfread('Subject%d_2.edf');

end

is not working. Any help or suggestions would be very much appreciated.
