% ***** PART 1 *****

% Create 5x4 matrix
G = [ 	0.6 	 1.5 	 2.3 	-0.5	 ; 
	8.2 	 0.5 	-0.1 	-2	 ; 
	5.7 	 8.2 	 9.0 	 1.5	 ; 
	0.5 	 0.5 	 2.4 	 0.5	 ; 
	1.2 	-2.3 	-4.5 	 0.5	];

% Create a column vector as the second column of matrix G
A = G(:,2);

% Create a row vector(or a 1x6 matrix) with integer values in the range 10 to 15
C = 10:15;

% Create a 2x6 matrix using the range operator
D = [ 4:9; 1:6 ];

% Create a row vector with values ranging from 0.0 to 1.0 incrementing by 0.1
F = 0.0:0.1:1.0;

% Create a sub-matrix of G consisting of rows 4-5 and columns 1-3
T1 = G( 4:5, 1:3 );

% Create a sub-matrix of G consisting of odd numbered rows and all columns
T2 = G( 1:2:5, :);


% ***** PART 2 *****

% Create row vectors A and B
A = [ 2	-1  5  0 ];
B = [ 3	 2 -1  4 ];

% Add matrices A and B, then subtract a row vector of 3.
C = A + B - 3;

% Element-by-element divide of matrices A and B
D = A ./ B;

% Raise matrix A to the power matrix B, then add twice matrix A
E = 2*A + A.^B;

% Raise matrix 2 to the power matrix B, then add matrix A
F = 2.^B + A;

% Double matrix B then divide by 3 times matrix A
G = 2*B / 3.*A;
