How to run simulink model from gui written in script?

I am running my simulink models from GUI,where Gui i have developed using MATLAB script,,,,and am controlling my stop time of both models through script ,,but am unable to do this,, Getting error like""""""Error using FinalTest/pushbutton2_Callback (line 115) Invalid StopTime specified in the Configuration Parameters dialog for block diagram 'course_speed_position'

Error while evaluating uicontrol Callback"""""This is my error ,,anybody help me?

If I give my stop Time ,some constant value,,its tasking,,but its not taking variable for stop time through MATLAB Script

[TAB]

How are you setting StopTime ?

Are you using set_param() ?

[Arun Badigannavar]

for i=1:25;,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, set_param('course_speed_position','StopTime', 'i'),,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,end,,,,,,,,,,,,,This is how am setting it

[Arun Badigannavar]

in set-param if i give constant value it ill work nut i want control it throuh vqariable

Answer 1

[TAB]

Try this, set_param() expect the value in string. So convert the value of i to string then pass it to set_param().

for i=1:25
  set_param('course_speed_position','StopTime', sprintf('%d',i));
end

Thank you ,,its working

Through script, you can do this by before using sim('your model name'); Mention the Tstop=10 or any, then you can change this value for your need...

[Arun Badigannavar]

for i=1:1:25; set_param('course_speed_position','StopTime', 'i'); set_param('course_speed_position1','StopTime', 'i'); % pause(0.) simOut = sim('C:\Documents and Settings\admin\Desktop\New Folder (5)\02_12_2012(Simulink blocks)\Resolved Models\Speed+Position+Course\course_speed_position.mdl'); simOut1 = sim('C:\Documents and Settings\admin\Desktop\Trial Testing\course_speed_position1.mdl'); end,,,,this is how am settingg the stop time ,,,
