Display waitbar

h = waitbar(x,'title')

Description

A waitbar shows what percentage of a calculation is complete, as the calculation proceeds.

h = waitbar(x,'title')

creates and displays a waitbar of fractional length x. The handle to the waitbar Figure is returned in h. x should be between 0 and 1. Each subsequent call to waitbar, waitbar(x), extends the length of the bar to the new position x.

Example

waitbar is typically used inside a for loop that performs a lengthy computation. For example,

h = waitbar(0,'Please wait...');
for i=1:100, % computation here %
waitbar(i/100)
end
close(h)
