%Problem 1: Create 3-by-3 matrix m, then copy the second and third rows of the matrix twice to create 4-by-3 matrix, then %(a) Delete 2nd row. %(b) Find sub-matrix of order 2-by-2. %-------------------------------------------------------------------

% Q1. In each case find the values of expression in Matlab and explain precisely the order in which calculation was performed:- % Part (a) a = -2^3 + 9; % Part (b) b = 2/3 * 3; % Part (c) c = 3 * (2/3);
