Homework Calculate using the approximation n=0 nl is the factorial: n!1x 2x 3x n ..n, n is odd the sefacoia: xxsbconfused with (n), which is not to be confused with (n!)!, which is the factorial function iterated twice. The semifactorial of n is the product of the integers between 1 and n which have the same parity (even or odd) as n. For example, 7!! = 1357 = 105, and 8!! 2x4x6x8-384 MATLAB has a built-in factorial function, but you will need to write the semifactorial function yourself. The sum given above goes to infinity. Your MATLAB function should take a single input argument which specifies how many terms of the summation should be computed
