Chapter 2, Problem 38E

To determine

To create:

The variables for these two matrices and perform these operations “A+B”, “A-B” and “A.B”.

Expert Solution & Answer

Answer to Problem 38E

Solution:

The variables for the given two matrices are “A = [1:1:3; 4 -1 6]”, and “B = [2 4 1; -1 3 0]” and the output of these operations “A+B”, “A-B”, and “A.B” are [364526], [−1−223−46], and “Error using . ” respectively.

Explanation of Solution

The given matrices are,

A=[1234−16]

And,

B=[241130]

Substitute [1234−16] for A and [241130] for B in the expression “A+B”.

A+B=[1234−16]+[241130]=[1+22+43+14+1−1+36+0]=[364526]

Therefore, the elements of the matrix “A+B” are [364526].

Substitute [1234−16] for A and [241130] for B in the expression “A-B”.

A−B=[1234−16]−[241130]=[1−22−43−14−1−1−36−0]=[−1−223−46]

Therefore, the elements of the matrix “A-B” are [−1−223−46].

Substitute [1234−16] for A and [241130] for B in the expression “A*B”.

A*B=[1234−16][241130]

The multiplication of the matrix is not possible.

Now, verify the expression output through the MATLAB command.

MATLAB Code:

A = [1:1:3; 4 -1 6]

% Define the command to get the matrix “A”.

B = [2 4 1; -1 3 0]

% Define the command to get the matrix “B”.

A+B

% Define the command to get the output of the expression “A+B”.

A-B

% Define the command to get the output of the expression “A-B”.

A*B

% Define the command to get the output of the expression “A*B”.

Save the MATLAB script with name, chapter2_45251_2_38E.m in the current folder. Execute the program by typing the script name at the command window to create the variables for given two matrices and perform the following operations “A+B”, “A-B” and “A*B”.

Result:

Therefore, the variables for the given two matrices are “A = [1:1:3; 4 -1 6]”, and “B = [2 4 1; -1 3 0]” and the output of these operations “A+B”, “A-B”, and “A.B” are [364526], [−1−223−46], and “Error using .” respectively.
