20. 
Why it can’t be
operated??

21. ∗ Open new file
1. %Proses Tambah
2.a = str2num(get(edit1,'string'));
3.b = str2num(get(edit2,'string'));
4.c = a + b;
5.set(edit3,'string',num2str(c));
∗ Save dengan callback-nya “prosestambah.m”
Membuat fungsi pada button

22. pen new file
Proses Pengurangan
= str2num(get(edit1,'string'));
= str2num(get(edit2,'string'));
= a - b;
et(edit3,'string',num2str(c));

23. • Open new file
1. %Proses Perkalian
2.a = str2num(get(edit1,'string'));
3.b = str2num(get(edit2,'string'));
4.c = a * b;
5.set(edit3,'string',num2str(c));
• Save dengan callback-nya
“proseskali.m”

24. • Open new file
1. %Proses Pembagian
2.a = str2num(get(edit1,'string'));
3.b = str2num(get(edit2,'string'));
4.c = a / b;
5.set(edit3,'string',num2str(c));
• Save dengan callback-nya
“prosesbagi.m”

25. • Open new file
1. %Proses Perpangkatan
2.a = str2num(get(edit1,'string'));
3.b = str2num(get(edit2,'string'));
4.c = a ^ b;
5.set(edit3,'string',num2str(c));
• Save dengan callback-nya
“prosespangkat.m”
