Matrix Decomposition / Matrix Factorization

Many mathematical objects can be understood better by breaking them into constituent parts.

Just like how we can decompose regular numbers into prime factors, we can try decomposing a matrix.

Methods:

• Eigendecomposition
• LU Factorization
• QR Factorization
• Singular Value Decomposition
