Handy progress bar that can be used in GUI or text interface.
  • Faster than waitbar (MATLAB builtin)
  • GUI interface
  • Figure automatically closes when the task is complete
  • CLI interface
  • Monospaced fonts are recommended for the CLI interface
  • Parfor compatibility
  • It uses parallel.pool.DataQueue
  • No file I/O, no java class, no undocumented matlab for parallel progress tracking
  • Support for legacy MATLAB releases
  • Standard version: MATLAB 2020b ~ latest
  • Legacy-compatible version: MATLAB 2017a ~ latest
Simple usage
Task name, Parfor
Text based progress bar
Faster than waitbar (MATLAB builtin)
N = 500000;
WB = waitbar(0,'waitbar'); % waitbar (MATLAB builtin)
for n = 1:N, waitbar(n/N,WB); end
close(WB)
PB = ProgressBar(N); % ProgressBar gui
for n = 1:N, PB.count; end
PB = ProgressBar(N, ui='cli'); % ProgressBar cli
for n = 1:N, PB.count; end
Elapsed time @ 2021 MacBook Pro 14" (M1 Pro)
