• Built-in tracking
• Elapsed time, estimated completion time, and MATLAB memory usage

🚀 Quick Start

1. Console (default horizontal)

N = 100;

p = ProgressBar(N);

for i = 1:N

pause(

0.05); % your work

p.update(

i);

end

p.finish;

2. Console vertical log

p = ProgressBar(20,'style','vertical');

for i = 1:20

pause(

0.1);

p.update(

i);

end

p.finish;

3. GUI waitbar

p = ProgressBar(100,'gui',true);

for i = 1:100

pause(

0.02);

p.update(

i);

end

p.finish;

4. Parallel parfor

N = 200;

p = ProgressBar(N,

'style','vertical'); % also 'horizontal' or 'gui'

dq = p.attachParfor();

parfor i = 1:N

pause(

0.01); % your work

send(dq,

1); % notify one step completed

end

p.finish;
