Matrix Theory: A Comprehensive Introduction. Exploring symmetric matrices, rank, eigenvalues, and fundamental theorems.

Symmetric and Skew-Symmetric Matrices. Symmetric Matrix.

Hermitian and Skew-Hermitian Matrices. These matrices extend symmetric concepts to complex numbers using conjugate transpose..

Elementary Operations on Matrices. These operations help simplify matrices while preserving important properties..

Rank of a Matrix. The rank reveals the number of linearly independent rows or columns in a matrix..

Matrix Inverse and Linear Dependence. Matrix Inverse.

Eigenvalues and Eigenvectors. These reveal special vectors that maintain direction under matrix transformation..

Minimal Polynomial. The minimal polynomial is the simplest polynomial that "annihilates" a matrix..

Cayley-Hamilton Theorem. This powerful theorem states that every matrix satisfies its own characteristic equation..

Unitary and Orthogonal Matrices. Orthogonal Matrix.
