How can I change a parameter in a Simulink block using code setVariable?

I do a simply circuit simulation, a voltage source DC and a resistence, i create 2 variables A = amplitude DC source and R = resistance, when try change this variables ony change A but R not change in the block so the out is not the rigth.

I do this

In = Simulink.SimulationInput('Sim');

In = In.setVariable('A',10);

In = In.setVariable('R',20);

In = simulink.compiler.configureForDeployment(In); % I need this

out = sim(In);

From what I understand, you're trying to update the variables 'A' and 'R' programmatically, but the variable R is not updating as expected. Can you share the model you're working on so that I can recreate the issue and investigate further?

I need create an app web with this simulation, so if I change in the app R value, in the simulation should change too but the code dosn't work well.

Since the variables you are trying to change are in the Model Workspace, you need to add an optional argument specifying this.

In = In.setVariable('R',2, 'Workspace', 'RL')

In = In.setVariable('A',20, 'Workspace', 'RL')

I tried that but didn't work

Thanks.
