A MathVector object will be passed to your method. Return the 5th element inside of that object. If you look in the file MathVector.java you'll see there is a way to extract the value of one element in the array contained inside a MathVector object: /** Returns the element at the specified index. @paran index the index of the element to return (greturn the element at the specified index / public int at(int index) \{ \} return array[index]; use it like myObject.at(4); to get the 4th element. You did similar operations (with a different syntax) with Matlab. What to reproduce this on your own machine?
