Hi all! I need to check the existence of a set of files with names as mentioned bellow.
data-0.0100-value-0.1000.dat
data-0.0200-value-0.2000.dat
data-0.0300-value-0.3000.dat
data-0.0400-value-0.4000.dat
data-0.0500-value-0.5000.dat
.
.
.
I know I can use 'exist' command to check the existence. But, I try to check using a for loop. In that case, I didn't know how to insert a variable in 'exist' command. I tried the following command:
c= 0.0100;
rr = 0.1000;
if exist('data-%4.4f-value-%4.4f.dat','file',c,rr) == 2
ddd=0;
end
I am getting error "Error using exist;Too many input arguments."
So how can I insert a variables in exist command? thanks in advance.
regards, raman

You can use sprintf
if exist(sprintf('data-%4.4f-value-%4.4f.dat',c,rr),'file') == 2

what does 'file' stand for?
i understand c & rr are the two variables inside the sprintf but what is file?
Thank you in advance.
