for i = 1:30
fid = fopen('%d.asc', i, 'r');
C = textscan(fid, '%s%s', 'Delimiter',',', 'HeaderLines', 1);
for k = 1:1046
E(k,1) = E(k,1) + str2double(string(C{1,1}(k,1)));
E(k,2) = E(k,2) + str2double(string(C{1,2}(k,1)));
end
fclose(fid);
end
E = (1/30) * E;
E
The code worked fine with reading just one file but it started giving permission errors when I put it in a loop.
The exact error message was :
Error using fopen
Invalid permission.
Error in physexp1 (line 2)
fid = fopen('%d.asc', i, 'r');
How would I fix this?
Thanks

Hi,
It might be an unappropriate way to format string using specifiers inside fopen. Instead you can try specifying filename seperately inside for loop and give that as input to fopen.
for i = 1:30
filename = sprintf('%d.asc', i);
fid = fopen(filename, 'r');
fclose(fid);
end
