How to use my own function within a guide file?
in [Matlab]

From: carlos on 26 Apr 2010 18:31 Hello everyone, I try to explain properly hehe. I need to add a function, created by myself, within a guide file (.m). I've got one button and three edit texts where in two of them I insert two numbers. After a click on the button, the third edit text must show the outcome of my function. The problem appears when I do click, the outcome in the last edit text is NaN. I don't know how i can do it cause I've used the command num2str but it doesn't work :S Could you help me?? My function is more complicated but i give you an example: function a=sumar(n1,n2) a=n1+n2; end CHEERS!!!
From: Image Analyst on 26 Apr 2010 20:50 carlos: Assuming you've read the two edit fields and converted them successfully into two numbers n1 and n2, then your function should work. Back in the calling function you'll need to do something like % In the push button callback: num1=str2double(get(handles.edit1, 'string')); num2=str2double(get(handles.edit2, 'string')); a1 = sumar(num1, num2); set(handles.edit3, 'string', num2str(a1)); That should work. If it doesn't, you might have to post your actual code. Maybe you didn't convert to numbers properly and you're trying to add two strings together or something illegal.

Before all, thank you for helping me!!! I've tried to do your recommendations but it doesn't work yet. Perhaps my conversion to layman's terms is my fault. Below, I attach you my guide "script" and afterwards my own function "script".

I forgot something. These "scripts" are in different files. The former one is called valorador.m(and the co-named valorador.fig) and the latter one is called as the function put_europea.m. Cheers!!

Finally I've got it!!! I had several problems with the formats. Thanks for your time, you are so great! |
