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.
