Given the following MATLAB statements 1 2 3 3 2 1 1 1 2 3 4

Given the following MATLAB statements: [1 2 3; 3 2 1] [1 1 2; 3 4; 5 6] [1 2 1; 2 3 2] [3 4; 2 1] [3 2 -1; -1 3 2; 1 -1 -1] [10; 5; -1] Compute the value of the result for each of the following expressions: A B A C D 2 D 2 Write a MATLAB expression to accomplish the following: Solve the system of equations given by E and R using the Inverse method Solve the system of equations given by E and R using the Left Division method

Solution

>> A = [1 2 3;3 2 1];
>> B = [1 2;3 4;5 6];
>> C = [1 2 1; 2 3 2];
>> D = [3 4; 2 1];
>> E = [3 2 -1;-1 3 2;1 -1 -1];
>> R = [10;5;-1];
>> A*B
