To create:
• The variable for the given matrix
• The variable for the given two matrices
• To find whether other multiplication operation can be performed in part 2 or not.
Answer to Problem 45E
Solution:
• The variable for the given matrix
• The variable for the given two matrices
• The variable for the given two matrices
Explanation of Solution
• The variable for the given matrix
The given matrices are,
And,
Substitute
Therefore, the elements of the matrix “3*A” are
Now, verify the expression output through the MATLAB command.
MATLAB Code:
A = [1 4; 3 2]
%Define the command to get the matrix “A”.
3*A
%Define the command to get the output of the expression “3*A”.
Save the MATLAB script with name, chapter2_54793_2_45_1E.m in the current folder. Execute the script by typing the script name at the command window to create the variable for the given matrix
Result:
Therefore, the variable for the given matrix
• The variable for the given two matrices
The given matrices are,
And,
Substitute
Therefore, the elements of the matrix “A*C” are
Now, verify the expression output through the MATLAB command.
MATLAB Code:
A = [1 4; 3 2]
%Define the command to get the matrix “A”.
C = [3 2 5; 4 1 2]
%Define the command to get the matrix “C”.
A*C
%Define the command to get the output of the expression “A*C”.
Save the MATLAB script with name, chapter2_54793_2_45_2E.m in the current folder. Execute the script by typing the script name at the command window to create the variable for the given two matrices
Result:
Therefore, the variable for the given two matrices
• To find whether other multiplication operation can be performed in part 2 or not.
The given matrices are,
And,
Substitute
Therefore, the elements of the matrix “C*B” are
Now, verify the expression output through the MATLAB command.
MATLAB Code:
C = [3 2 5; 4 1 2]
%Define the command to get the matrix “C”.
B = [2 1 3; 1 5 6; 3 6 0]
%Define the command to get the matrix “B”.
C*B
%Define the command to get the output of the expression “C*B”.
Save the MATLAB script with name, chapter2_54793_2_45_3E.m in the current folder. Execute the script by typing the script name at the command window to create the variable for the given two matrices
Result:
Therefore, the variable for the given two matrices
