File name a function argument

Hello there,

I hope every body is doing file. I have two questions. I will be very grateful if any matlab advance user can reply me.

1. Could you please tell me how I can use file name (say, aba.txt, actually data in text file) as Argument in a Matlab Function?

2. Can I call .m file ( not function, just code) inside another .m file? If yes, could you please suggest me, how I can do that.

Thanks in advance Regards Shafi

1. Which is it? Do you want to have the filename passed or the data in the file?

2. Do you mean that you want to call a script M-file as opposed to a function M-file? Simply put the name of the script wherever you would like to run it.

1. the standard approach would be to use a string

function y = foo(fname)
fid = fopen(fname);
etc

Then call it with

x = 'abc.txt';
y = foo(x);

2. yes, just give the name of the script (without the .m extension) as a command, just like you'd run it at the command line.
