Thread Subject: File names from char array?

Hi everyone,

I was wondering if anyone knew how to extract a filename from a character array?
I am currently modifying a program and have changed it to run multiple runs without user input (one additional external loop).

Now what i would like to do is input the filenames that i will be outputing to in an array:
fnameindex = ['609-1.txt'; ...
             '610-1.txt'; ...
             '611-5.txt'; ...
             '612-1.txt'; ...
             '617-4.txt'; ...
             '618-5.txt'];
    fname=cellstr(fnameindex);

but when i try and use the: '609-1.txt' as a filename in fopen(fname(1),'wt') it gets an error.

is there a better way to do this? or am i just going to have to type this in each required part of my program?

Thanks in advance,
Michael.

fopen(fname{1},'wt')

Thanks for your reply... i figured this out right as i saw your responce... aparently the {} and () make all the difference with char's

Thanks again-
Michael.
