Write a user-defined function, with two input augments (a, b) and two output arguments (max1, max2) such that max1 is the maximum element of the first two rows of matrix a, and max2 is the maximum element of the last two columns of matrix b.
use a = [ 3 4 6; 2 8 5 ; 2 7 9 ] and b = [ 6 0 4; 4 1 3 ; 9 2 5 ] to test your function and show the results.

Write a program that prompts the user to input a string. the program then uses the function substr to remove all the vowels from the string. for example, if str = "there", then after removing all the vowels, str = "thr". after removing all the vowels, output the string. your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.
