use matrix algebra in matlab

Matlab provides a simple and efficient way to perform matrix algebra operations using built-in functions. The following are some examples of how to use matrix algebra in Matlab:

1. Matrix Addition and Subtraction:

You can use the "+" and "-" operators to perform matrix addition and subtraction.

A = [1 2 3; 4 5 6; 7 8 9];
B = [9 8 7; 6 5 4; 3 2 1];

C1 = A + B; % Matrix addition
C2 = A - B; % Matrix subtraction

2. Matrix Multiplication:

You can use the "*" operator to perform matrix multiplication.

A = [1 2; 3 4];
B = [5 6; 7 8];

C = A * B; % Matrix multiplication

5 lines

3. Transpose of a matrix:

You can use the "'" or "." operator to get the transpose of a matrix.

A = [1 2; 3 4];
B = A'; % Transpose using "'."
C = transpose(A); % Transpose using "."

4. Inverse of a matrix:

You can use the "inv" function to get the inverse of a matrix.

A = [1 2; 3 4];
B = inv(A); % Inverse of A

5. Determinant of a matrix:

You can use the "det" function to get the determinant of a matrix.

A = [1 2; 3 4];
d = det(A); % Determinant of A
