variable sweep in simulink

How do I sweep the value of a "gain block" in simulink? can I do a few iterations, each one with different value in the gain block? Thanks

Hi!

How do sweep current and voltage in a simulink model?

in simulimnk change the name of the gain parameter to for example G. The value for G can then be specified from the workspace. So you can use a for loop like this one:

 gain=[1:20];
 for n=1:length(gain)
  G=gain(n);
  run('simulink_model_name')
 end

using parfor instead of for can improve performance if you have a multiple core machine.

hope this helps

Update: If you are using R2017a or later, the parsim command can be used to set this up very easily.
