How to design Radio button, check boxes and drop down menu in MATLAB App Designer? 

Thanks for your comments. For toggle button usage you can refer to my below video : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CUvby20tExk.html I hope it is helpful.

Unused variables in a function should not cause any issue or error. At best it will throw some warning messages. Anyway, you can also avoid initializing these variables (Nt, Nv). If these variables are defined as output of some other computation/ function then simply put tilde (~) symbol instead of variable name. This way you can avoid initializing these variables. Say in below example: >> a=2; >> b=3; Instead of : >> Nt = a+b Nt = 5 Use: >> [~] = a+b Hope the above helps.

There is no direct way to link 3 text fields in App Designer. To solve your requirement, what you can do is to assign the output value of all the three text fields using same variable in your callback code. To automate this what you can do is to define update callback function for any of the text field. And in this function you can assign other text fields output values as well. Take an internal class variable to do all these stuffs. It will be easy. The above should be very easy to implement. I hope you succeed.

Thanks 😀. Regarding transfer function, I think it should be simple. You can take the numerator and denominator separately as input from text boxes in your gui. And then you can use tf matlab command in your callback code to convert it into transfer function. The details of tf command can be found in below link : mathworks.com/help/control/ref/tf.html I hope the above explanation is helpful to you.
