[Rounak Saha Niloy]

The following code worked fine for me.

A=D';
for i = 1:7500
    fid = fopen([num2str(i),'.txt'],'w') ;
    fprintf(fid,'%f\n',A(i,:)) ;
    fclose(fid) ;
end

A = rand(3,10) ;
for i = 1:3
    fid = fopen([num2str(i),'.txt'],'w') ;
    fprintf(fid,'%f\n',A(i,:)) ;
    fclose(fid) ;
end

A=randi(100,3,7500);
writematrix(A(1,:),'myfile1.txt')
writematrix(A(2,:),'myfile2.txt')
writematrix(A(3,:),'myfile3.txt')
