What Are Special Matrices? (Identity, Diagonal, Lower and Upper Triangular Matrices)

What are special matrices and what does special matrices even mean? Special Matrices are types of matrices that are easy and simple to solve. Special Matrix include identity matrix, lower triangular matrix, diagonal matrix, and upper triangular matrices. These will be extremely useful when we get into coding with these types of matrices.

The following timeline is meant to aid your understanding of Special Matrices:

Increased my knowledge of linear alegbra! Thankyou

[zeldovich]

I suggest to add the algorithm for xi solutions in the backward and forward substitutions, with the purpose of implement in a code
