(MATLAB PROGRAMMING) exercise 10.3

Write a MATLAB function that will accept a cell array of strings and sort them into ascending order according to alphabetical order. (This implies that you must treat A and a as the same letter.) Create a function that accepts any number of numeric input arguments and sums up all of individual elements in the arguments. Test your function by passing it the four arguments a = 10, b = [4 -2 2], c = [1 0 3 -5 1 2 1 2 0], and d = [1 5 -2] Modify the function of the previous exercise so that it can accept either ordinary numeric arrays or cell arrays containing numeric values. Test your function by passing it the two arguments a and b, where a= [1 4 -2 3] and b {1} = [1 5 2] and b{2} = [1 -2 2 1]. Create a structure array containing all of the information needed to plot a data set. At a minimum, the structure array should have the
