I am bad at Matlab any help is greatly appreciated type 'whos' into your command window. Notice that x is an array of price values, not a single value. fprintf prints one line for each element in x, thats why you see 'all these lines' Search the doc to find a function which takes an array as an input and returns one single max value, use this in place of x
