Write a function called normalizegrades that receives a row array of test scores of arbitrary length and positive values, and produces two outputs: a row array array containing the grades normalized to a linear scale from 0 to 100 (i. e. grades are normalized if the maximum grade equals 100). hint: use the internal function max. the average of the normalized grades. hint: use the internal function mean. restriction: loops may not be used. for example, following code: scores=[90, 45, 76, 21, 85, 97, 91, 84, 79, 67]; [normscores, average]=normalizegrades(scores) produces:
