Create functions, including anonymous, local, and nested functionsFunctions contain one or more sequential commands and can accept inputs and return outputs. When you have multiple lines of code, use the function keyword to define a function within a file. For instance, this function adds tax to...
Another option for storing functions is to include them in a script file. For instance, create a file namedmystats.mwith a few commands and two functions,factandperm. The script calculates the permutation of (3,2). x = 3; y = 2; z = perm(x,y)functionp = perm(n,r) p = fact...
