i got 3 errors here:
  • the function keyword use is invalid here
  • parse error at ')':
  • parse error at ELSE:
can somebody tell me how to fix this
pilih=get(handles.uibuttongroup1, 'Value');
handles.pilih=pilih;
guidata(hObject, handles)
if(pilih==1)
function[G] = ambang(F,t);
[m,n] = size(F);
for i = 1:m
for j = 1:n
if F(i,j) <=t
G(i,j) = 0;
else
G(i,j) = 1;
end
end
end
end
else if (pilih==2)
function[G] = arasjamak(F,t1,t2)
[m,n] = size(F);
for i = 1:m
for j = 1:n
if F(i,j) <=t1 || F(i,j) >=t2
G(i,j) = 0;
else
G(i,j) = 1;
end
end
end
end
else if(pilih==3)
level = graythresh(j);
BW = im2bw(j,level);
imshow(BW);
end

You cannot define a function inside an if statement. If you want to include a helper function, ir must be defined at the bottom of your script, or in a separate file. See here for more.
