In your implementation do you need to close and create a new waitbar? can you re-purpose the existing waitbar to encompass the other computation steps?
h = waitbar(0,'Please wait...');
steps = 1000;
for step = 1:steps
% computations take place here
waitbar(step/steps,h,['computing 1: ' num2str(step)])
end
for step = 1:steps
% computations take place here
waitbar(step/steps,h,['computing 2: ' num2str(step)])
end
for step = 1:steps
% computations take place here
waitbar(step/steps,h,['computing 3: ' num2str(step)])
end
close(h)
