Simple usage

Task name, Parfor

Text based progress bar

Faster than waitbar (MATLAB builtin)

N = 500000;

f = waitbar(0,'waitbar');             % waitbar (MATLAB builtin)
for n = 1:N, waitbar(n/N,f); end
close(f)

PB = ProgressBar(N);                  % ProgressBar gui
for n = 1:N, PB.count; end

PB = ProgressBar(N,[],'cli');         % ProgressBar cli
for n = 1:N, PB.count; end
