Question

I would like to set up a counter that informs me about a long iterative computation (e.g. in for).

Is it possible to set up this counter in a way that when it is updated on screen, it replaces the previous value?

That is, printing the iterator variable of a for is not ok, since Matlab either prints it into a new line, or after the previous value, but after 10000 iterations the screen would be filled either way. Also, I would like to update the counter in each turn.

Answer 1

fprintf('\n')
for i=1:15
    fprintf([repmat('\b', 1, length(num2str(i-1))) '%d'], i)
    pause(0.1)
end
fprintf('\n')
