This function is an adaptation of Steve Hoelzer's progressbar.m function. It provides similar features, but with improvements to behavior when utilizing multiple task bars as well as several bug fixes. Many thanks go out to Steve for his initial ground work and for inspiring this function.

- Provides a graphical representation to indicate task completion for
loops and nested-loops. (Time remaining and percentage complete).
- Supports multiple taskbars in a single figure (nested-loops).
- Provides enhanced execution times when compared to similar functions.
- Progress() function can be used with minimal lines of code.
- Simple to update, add, remove, and/or rename/reset taskbars to the
main figure.
- Optional taskbars labels.
- Figure closes automatically when primary task is 100%.
- Only one progress bar figure can exist to prevent desktop clutter.
- Displays progress bar figure on top of other windows.
(Designed for Windows 8 and may not work with other systems.)
- Progress bar figure can be deleted during a loop without errors.
- Works in loops that target other axes objects.
- Display options for taskbar color and font.
- Randomizes taskbar color when mouse-clicked. For Fun!

m = 1e3;
n = m/2;
o = 1e4;
t = 0.0005;

Opts = {'color','cyan',...
'fontcolor',[1,0,0]}; % Display options [cell]
Progress('Plotting',Opts) % Initializes figure with 1 taskbar and display options
x = 0:0.005:2*pi;
np = length(x);
for i=1:np
plot(x,sin(x+6*x(i)),x,cos(x+13*x(i)));grid on
Progress(i/np) % Updates the taskbar progress

Opts = {'color',[0.3,0.3,0.3],...
'fontcolor','green'}; % Display options [cell]
Progress('Task 1','Task 2',Opts) % Initializes figure with 2 taskbars and display options
for i=1:m
Progress(i/(m+n),i/m) % Updates both taskbars

Progress([],'Task 3') % Renames/resets the 2nd taskbar
for i=1:n
Progress((m+i)/(m+n),i/n) % Updates taskbars 1 & 2 (removes all others if present)
if i==n/2
Progress([],[],'Task 4') % Adds a 3rd taskbar
for j=1:o
Progress((m+i+j/o)/(m+n),(i+j/o)/n,j/o) % Updates all 3 taskbars
