Hi all,
I am using the "forward dynamic" tool to solve a "dynamic optimization" problem using MATLAB optimization toolbox.
As it's a dynamic optimization, it has lots of forward integrations and for each of them, the forward dynamic tool prints lots of data on cmd screen (An example of the printed data is provided at the end of this message.)
I am pretty sure that if I could turn this feature off, I would save time.
I tried " forward -S setup.xml > null" but it did not helped. Because it writes the same data in a file which is time consuming as well.
Is there any way so that I can turn this printing feature off?

Hi Sina,

The messages are written to stdout (in Programming terms), so if you can redirect that from within Matlab it should work, otherwise please file a feature request (from the application's Help->Request Features menu) and we'll try adding an option to work in quiet mode where info messages are not printed to stdout. Other than cluttering the screen, are there any more difficulties caused by these messages?

Best regards,

Hi Ayman
Unfortunately it seems that it is not possible to redirect it from matlab. I will send a feature request,
The problem is not clutter on the screen, but the time. For my specific forward dynamic problem, if I could turn off the screen display, I would save 20% of total time. For my final full scale runs which would take around 2 weeks, I will save 3 days for each run.

Regards,
Sina
