Common Matrix Operations in MATLAB

1. Matrix Addition and Subtraction

Matrix addition and subtraction in MATLAB are straightforward. Ensure that the matrices are of the same dimension:

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

C_add = A + B;
C_sub = A - B;

2. Matrix Multiplication

Matrix multiplication is executed using the * operator. It’s essential for tasks involving linear transformations and solving systems of linear equations:

D = A * B;

For element-wise multiplication, use the .* operator:

E = A .* B;

3. Transposing a Matrix

Transpose a matrix to switch rows and columns, crucial for diversifying data perspectives:

F = A';

4. Inverting a Matrix

Inverting a matrix is a critical operation for solving linear equations using the inverse method:

G_inv = inv(A);

However, ensure that the matrix is not singular (determinant ≠ 0).

5. Determinant of a Matrix

The determinant provides valuable insights into matrix properties, such as invertibility:

det_A = det(A);

Advanced Matrix Manipulations

In modern MATLAB versions, additional functions provide efficient ways to handle matrices:

  • Eigenvalues and Eigenvectors using eig() function can be manipulated for matrix diagonalization and stability analysis.

    [V, D] = eig(A);
  • Singular Value Decomposition (SVD) is pivotal in data reduction, noise reduction, and system identification.

    [U, S, V] = svd(A);
