MATLAB: How to access value from gui to simulink subsystem for mask resistor ???

guiMATLABsimulink

i want to change my resistor value from gui… i gave for example set_param('MyModel/MySubsystem/MyBlock','resistance','10'); but it shows Myblock does not have resistance parameter.. help me to solve this problem

To get the reals names of your parameters type

get_param('MyModel/MySubsystem/MyBlock','DialogParameters')

The name of the parameter you want to change is R, not resistance.

set_param('MyModel/MySubsystem/MyBlock','R','10')

This is the expected behavior.

It is because the masked subsystem has its "MaskSelfModifiable" parameter set to "on".

If you set this parameter to be "off", by using the command:

set_param('block','MaskSelfModifiable','off')

The issue will be fixed.

Note that the masked subsystem should not change itself, so its "MaskSelfModifiable" parameter should be set to "off".

Try this :

r3 = 100; % for example
Volt_func =  @(r)1.24*(r(1)*r(2)+r(2)*r3+r3*r(1))/r(1)/r(2);
rout = lsqnonlin(Volt_func,[50,55])
r1 = rout(1);
r2 = rout(2);

Note : "lsqnonlin" can only be used if you have optimization toolbox. If not, there are few other functions that don't need optimization toolbox.
