Hey everyone.

I have a function that analyses an image and returns numerical values about it in several variabels.

Imagine I run my code and have the following data

a1=2; a2=4; a3=0; a4=8;

now I want my code to write this values in a .txt in the following way: 2,4,0,8

I want to be capable of analysing several images in the folder and to keep all the results in the same .txt file, with all the values separated by commas.

Thanks in advance!

在 MATLAB Online 中打开

This opens the file once (overwriting if it already exists) and writes your results one line at a time.

fid = fopen( 'results.txt', 'wt' );
for image = 1:N
  [a1,a2,a3,a4] = ProcessMyImage( image );
  fprintf( fid, '%f,%f,%f,%f\n', a1, a2, a3, a4);
end
fclose(fid);
