Finding Object Parameters for controlling Simulink object through "set_param()"

Asked by Jeevan Thomas on 22 Apr 2014

I was looking at controlling (toggling) the "manual switch" block in Simulink through M-scripts (matlab commands).
I was able to do so using the following command:
set_param(gcb, 'sw','0');
set_param(gcb, 'sw','1');
I was able to Google the right parameter (as listed above) in case for manual switch.
Now the question is, from where do I find that manual switch" has a parameter of "sw" to control it using the set_param() function?
I've tried
get_param(gcb, 'DialogParameters')
get_param(gcb, 'ObjectParameters')
Both the above functions doesn't list "sw" as a parameter for "manual switch".
I'm using Simulink on Matlab R2012b

Hi Jeevan,
I think
get(gcbh)
and
set(gcbh, 'sw', '0')
will do what you're after.

Hello Graham,
Thank you for your response. Your solution works fine.
But my question is regarding the "sw" argument that you used in
set(gcbh, 'sw', '0')
How do I find that a "Manual Switch" block in Simulink has "sw" attribute?
Tried the following and none of if shows the above "sw" attribute:
get(gcbh)
get_param(gcb, 'DialogParameters')
get_param(gcb, 'ObjectParameters')
Hope my question is clear this time.
Thank you once again.
rgds,
JT

Hi Jeevan, I tried get_param(gcb, 'DialogParameters') and get_param(gcb, 'ObjectParameters')
Both of them show a parameter called sw in Matalb2010b. Even the BlockProperies>BlockAnnotations of Mannual Switch shows %<sw> in it.
