I want to write output of code periodically in different files in some specific folder. Code I am using is as follows:
for i=1:m % some other things if (mod(i,1000)==0) y=[1:dx:n_x;c_initial.']; fn = ['/home/alekhine' num2str(i) '.dat']; fid=fopen(fn); fprintf(fid,'%6.4f %12.8f\n',y); fclose(fid); end end
But I am getting error from Matlab as follows
Error using ==> fprintf Invalid file identifier. Use fopen to generate a valid file identifier.
. What is wrong in the code? Any help will be appreciated.
You seem to be missing a path separator in the path generation:
fn = ['/home/alekhine' num2str(i) '.dat'];
fn = ['/home/alekhine/' num2str(i) '.dat'];
