Hello, I need to save a .txt file with data of a matrix M like
1 1 -52.56 -92.20 28.94
1 2 -22.57 -92.19 28.01
2 1 -39.96 -92.20 44.76
2 2 -12.22 -92.08 33.33
3 1 -22.83 -92.20 55.49
3 2 -0.66 -92.03 35.27
I use this script
fid = fopen('curve_back.txt','wt');
fprintf(fid,'%0.0f %0.0f %0.2f %0.2f %0.2f\n',M');
fclose(fid);
but I'd like to save numbers with comma separator instead of point symbol. Any hint? Thanks.

Here's one way,
T=strrep(evalc('disp(M)'),'.',',');
fid = fopen('curve_back.txt','wt');
fwrite(fid,T);
