[Walter Roberson]

fid =fopen('C:\Users\TOSHIBA\res.txt', 'w' );
fwrite(fid, test);
fclose(fid);

However, if "test" is numeric, use

fprintf(fid, '%g\n', test);

instead of fwrite(). This format would put one value per line.

[n]

so so Thanks MR

this "fprintf(fid, '%g\n', test);" outputs values in scientific notations 2.33472e+06 instead of 233472.
