Question

second picture is output of the mathlab code

Important Note: For testing of this part of the assignment, the automatic printing of values in the com mand window must not be used. Please make sure you put semicolon ω at the end of each line. For this part your program should perform following tasks 1. Create a Matrix A. Show the contents of matrix A to command window with the title Matrix A:". The Matrix A should be defined as following 22 0 124 2. Create a Matrix B. Show the contents of matrix A to command window with the title "Matrix B: The Matrix B should be defined as following 14 4 -3 9 3. Select row1 in matrix A using colon operator. Show the output to command window with the tle Row 1 in Matrix A: 4. Select column 2 in matrix Busing colon operator. Show the output to command window with the title Column 1 in Matrix B: 5. Use the built-in sum function to find the sum of each row in matrix A Show the result to the com mand window with the title "Sum of matrix A:" 6. Add the matrices A and B. Show the results to the command window with the title "Adding matni ces A and B: 7· Find the Vector (element-by-elernent) multiplication of A and B. Show the results to the command window with the title Vector multiplication of A and B: 8. Find the matrix multiplication of A and B. Show the results to the command window with the title Matrix multiplication of A and B:" 9. Find the matrix multiplication of B and A. Show the results to the command window with the title Matrix multiplication of B and A:" 10. Use the built-in min and max function to find minimum element of matrix A and maximum ele- ment of matrix B for each column. Then create a new matrix that first column is maximum of matrix B and second column is minimum of matrix A Show the result to command windows with the title Matrix from minimum of A and maximum of B: Matrix A: 22 0 12 4 Matrix B 14 4 3 9 Row 1 in matrix A: 220 Column 2 in matrix B: Sum of matrix A: Adding matrices A and B 36 Vector ultiplication of A and B 308 0 -36 -36 Matrix multiplication of A and B 2 308 88 180 12 Matrix multiplication of B and A 356 16 42 36 Matrix from ninimum of A and maximum of B 12 4

Answer 1

A = [22 0; 12 4]
B = [14 4; -3 9]
%matrix A
fprintf("Matrix ")
A
%matrix B
fprintf("Matrix ")
B
%matrix A's row1
fprintf("Row 1 in matrix A:")
A(1,:)
%matrix B's column2
fprintf("Column 2 in matrix B:")
B(:,2)
%addition
fprintf("Adding matrix A and B:")
A+B
%vector multiplication
fprintf("Vector multiplication of A and B: ")
A.*B
%Matrix multiplication
fprintf("Matrix multiplication of A and B: ")
A*B
fprintf("Matrix multiplication of B and A: ")
B*A
a=min(A(:,1))
b=min(A(:,2))
c=max(B(:,1))
d=max(B(:,2))
%new matrix
fprintf("Matrix from minimum of A and maximum of B")
newM=[c d; a b]
