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);
