Dear all,
I try to save an 512x512 matrix of lena image into text file, which will be used for fpga processing.
I have use the recommended code:
A = round(rand(6,7)*9) % Write this to file.
fid = fopen('Mymatrix.txt','wt');
for ii = 1:size(A,1)
fprintf(fid,'%g\t',A(ii,:));
fprintf(fid,'\n');
end
fclose(fid)
However, the output file miss many coefficients.
Is there any method to create an complete text file with tab between coefficients ?
Thank you

This code works perfectly. To check it add the following at the very end of the above code:
fid = fopen('Mymatrix.txt','r');
[A1,n]=fscanf(fid,'%g %g',[7 inf]);
fclose(fid);
fprintf(1,'Data being fed from the file is :\n')
A1'
and compare A1 with (the original data) A.
