Write a MATLAB function named sum_highest that adds up a specified number of the the largest values in a list of numbers. The first input will be a row vector of real numbers, the 2nd input will be an integer specifying how many largest numbers to add. The output should be a single real number that represents the sum of the subset of numbers. Hints: there is an operator that allows you easily specify a subset of a list there are built-in commands to sort in descending order and to sum the values in a matrix.
