22 Oct 2010 A CUDA accelerated Beam Propagation Method [BPM] Solver using the Parallel Computing Toolbox A beam propagation method solver using the CUDA capabilities in the parallel computing toolbox. Author: Patrick Kano

Hello, Patrick. It is quite a coincidence that I am working in this same subject (kind of). I do not have, however, the latest Parallel Computing Toolbox (PCTB) and I would like to do some questions. Do you choose to use CUDA over standard parallel computing (multicore) by any particular reason? Is the FFT2 parallelized in the new version of PCTB (as far as I know, I'm my version it is only parallelized 1D FFT)? I am using 2009b, by the way. Thanks!

Hi,

I use 'dispstat' function just for this purpose. It can update the previous output which is a missing function of default 'disp'. Very simple to use. It can be downloaded from here:

http://www.mathworks.com/matlabcentral/fileexchange/44673

***Sample usage:
dispstat('','init'); % One time only initialization
dispstat(sprintf('Begining the process...'),'keepthis','timestamp');
for i = 97:100
dispstat(sprintf('Progress %d%%',i),'timestamp');
%doing some heavy stuff here
end
dispstat('Finished.','keepprev');

***Output:
11:25:37 Begining the process...
11:25:37 Progress 100%
Finished.

All the best

Great function to let you know the integrator's progress. The best feature is it's simplicity.
It appears that the demo file wasn't included in this zip file, but it's very simple to use, just add it as an output function in the odeset command. Here's an example:
ops = odeset('OutputFcn',@odetpbar);
[t,y] = ode45(@DiffEqns,Timespan,InitConditons,ops);
