## Array indices must be positive integers or logical values

In programming, writing f(x) = x^2 + 1 would typically be understood as using indexing notation -- that the current numeric value of x is to be looked up, x^2 + 1 calculated, and the result to be stored in vector f indexed at the locations whose offset is in x. But your x (n in your case) values are not integers, and not many programming languages allow …Array indices must be positive integers or...
