MATLAB: Controlling manual switch through m-file

manual switch blockMATLABsimulinkswitch

there in a manual switch,which can be altered during run time.now if i want to alter the switch through m-file command.what to do?

It looks like this should work

set_param('path/to/block', 'sw', '0')
set_param('path/to/block', 'sw', '1')

I found the names of the block parameters using this command, and just picked the one that seemed likely:

>> get_param(gcb, 'DialogParameters') % select the block first with the mouse

The parameter is called 'sw', not 'varsize'. You need to use:

>> set_param('ecg_filter/sw1', 'sw', '0')
>> set_param('ecg_filter/sw1', 'sw', '1')

There is a solution:

p = Simulink.Mask.get(gcb); param = p.getDialogControl(<Name of your control in the mask>); param.Visible = 'off';
