Write a user-defined function that determines the mode of a set of data (the value in the set that occurs most often). For the function name and arguments, use m=mostfrq (x). The input to the function is a vector x of any length with values, and the output m is a two-element vector in which the first element is the value in x that occurs most often, and the second element is the mode. If there are two, or more, values for the mode the output is the message: "There are more than one value for the mode." Do not use the MATLAB built-in function mode. Test the function three times. For input create a 20-element vector using the following command: x = randi (10, 1, 20).
