for problem 1 use while loop, and for problem 2 and 3 use for end loop

need it urgently !

Problem 1 Write a Matlab program that asks the user to enter a number, of unknown number of digits, and find a. The square of the sum of the first and last digit. b.Divide the value obtained in part (a) by the number of digits Output: Enter any number: 1235 The square value = 36.00 The division value = 9 Problem 2 Write a Matlab program that prints a table with 5 lines of output. On output line number k, the program should list the numbers from k to 2k (line number times 2). Together with the sum of even numbers only. Note that there is a space between the printed numbers. You have to use loops to solve this problem. Same output is shown below (only first 4 lines are shown): 1 2 the sum is 2 2 3 4 the sum is 6 3 4 5 6 the sum is 10 4 5 6 7 8 the sum is 18 5 6 7 8 9 10 the sum is 24 Problem 3 Write a program that use loops to print the following pattern. Your program should use for loops to generate the patterns. 10 98 765 4 3 2 1
