Name:9.(5 marks total)Write aMatlabfunctionmyfactorialto compute the factorialN! = (1)(2)(3). . .(N)given a positive integerN≥1, i.e. the product of all integers between 1 andN. Assumethe input to the function is always a single positive integer and the output is a single realnumber (i.e., do not worry about testing input arguments or accepting arrays as input, andyou don’t have to consider the possibility of the input being 0).Assuming the function definition line for them-filemyfactorial.mis as given below, fill inthe rest of the function file in the space beneath.
