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

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.

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.
