System redesign via MATLAB

Hello,
Can I use the MATLAB API to redesign a system that was loaded from a *.awd file?
By redesign I mainly mean changing the Argument values of some inner modules. For example, changing the numOut argument value of a Deinterleave module from 2 to 3.

Thanks,
Sharon.

Hi Sharon,

Some variables are hidden by default in MATLAB, but you can type the text below to view these.

global AWE_INFO;

AWE_INFO.displayControl.showHidden = 1;

Then if you'd like to change a variable such as the numOut of a deinterleave  you can set that then run or  export the design from MATLAB. The API guide in the docs folder of your download uses the example of a Scaler's gain range on page 9 - 11:

GSYS.SYS.Scaler1.gain.range

ans = 

-24 24

Then you can change the gain range by typing:

GSYS.SYS.Scaler1.gain.range = [-50 0];

Then you can save to disk with:

save_awd('Example1.awd', GSYS);

Hope this helps. -Kyle
