In your code, once the following is true, it is always true, since you don't modify any of the variables inside the 'if'
if a(i) >= start && a(i-1) <= start && a(i+1) > a(i)
Thus, your variables i and m stay the same after this point, and you get stuck in an infinite loop.
Maybe you intended i to increase after each iteration regardless of the 'if'?
In this case, the following should work, though it doesn't result in the result you say is correct: [3 8]
while i < m
if a(i) >= start && a(i-1) <= start && a(i+1) > a(i)
fwd(f,1) = a(i);
for j = i+1:m-1
if a(j+1) > ed && a(j+2) >= a(j+1) && a(j) < a(j+1)
fwd(f,2) = a(j);
end
end
end
i = i+1;
end
It's difficult to get any closer to solving this without any explanation of what your code is supposed to do.
