Hi everyone..
I have a GUI and Simulink (from Simmechanics), and I want to import a data from Edit Text Box in GUI to Constant Block in Simulink. But I don't know how to make it. Is there anyone who can help me?
Thankyou for your attention...

Use 'assignin' function in GUI function callback for updating value of variable that is used in constant block.

c=10
set_param('yourmodelname/Constant','value',num2str(c))
%yourmodelname is your simulink model name

@ Azzi Abdelmalek
I used your command:
c=10
set_param('yourmodelname/Constant','value',num2str(c))
but it does not work with step block. Do you know the command for step block. thanks

hellos everyone . I am now working on a project that is the regulation of the temperautre and humidity with the help of the Arduino + DHT11 sensor and Simulink , I connected a script matlab in series with the Arduino software to extract values humidity and temperature to plots them in a graph. I'd like to display these values in Simulik for the regulation of these values ,I got Many problem at the declaration of set- param function here is the matlab code (exmeple Tepmerature ): global Temp ; Temp(i) = str2num(out(1:4));
set_param('DHT11SIM/Temperature','value',num2str(Temp))
set_param('DHT11SIM', 'Temperature', 'update')
subplot(211); plot(Temp,'g'); axis([0,temps,20,50]); title('DHT11 Température'); xlabel('---> temps (secondes)'); ylabel('---> Température'); grid
code simulink:
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/174449/image.png)
here is the erruer that always receives: Error using DHT (line 15) Invalid Simulink object name: DHT11SIM/Temperature .
please Help me
