MATLAB: How to get variables from GUI m-file into Simulink Model

Hey guys, I dont know if I'm wording my problem开发者_StackOverflow社区 right but I have created a GUI, an m-file and a simulink. Initially I had the variables going from the m-file into the Simulink, but now I want the user to be able to change the variables so I have created a GUI. I keep getting an error though, I dont think the variables are going from the GUI m-file to the simulink model anymore. I remember you had to set something to do it, like simset or setcurrentsim or something but I cannot remember, so I was wondering can anyone help me with this one?

Use the set_param command.

It should look something like this:

set_param('model name/block name','block type',string);

In my code I have a model called Pitch_Control with a Gain block called Pitch Rate Sensor. k2 is an integer.

set_param('Pitch_Control/Pitch Rate Sensor','Gain',num2str(k2));

I hope this helps.

set_param works, however it is a pretty specific way and should only be used to change block settings and not to pass parameters.

What you are looking for is assignin. You go with: assignin('base','Parametername',value); Since Simulink imports variables from the base-workspace it does the same as your old script would have done.
