There is no such thing as an "if loop". "if" executes the body exactly 0 or 1 times, which is not a loop; "for loop" and "while" (usually) execute multiple times.

Try this:

```minValue = inf; % Initialize to infinity
for k = 1 : 10
if array(k) < minValue;
% Surely you can fill in the rest!
end
end
```

It's probably too much of a hint but it's hard to do much less since it's so short and trivial.

Calling a variable "linelen5" is a bad idea and a standard mistake of beginners. Use an array instead: "linelen(5)" etc.

```linelen = [13, 14, 15, 16, 17, 18, 19, 113, 114, 115, 116]
shortestline = linelen(1)
for k = 2 : length(linelen)
```

etc.
