Sparse matrices

Pentadiagonal matrix

In linear algebra, a pentadiagonal matrix is a special case of band matrices.Its only nonzero entries are on the main diagonal, and the first two upper and two lower diagonals. So it is of the form It follows that a pentadiagonal matrix has at most nonzero entries, where n is the size of the matrix. Hence, pentadiagonal matrices are sparse, making them useful in numerical analysis. (Wikipedia).

Understanding Matrices and Matrix Notation

In order to do linear algebra, we will have to know how to use matrices. So what's a matrix? It's just an array of numbers listed in a grid of particular dimensions that can represent the coefficients and constants from a system of linear equations. They're fun, I promise! Let's just start
