Matrix and determinants

Matrix and determinants

1. Types of matrix

   • There are 6 different types
     • -Zero Matrix -Identity Matrix -Symmetric Matrix -Diagonal Matrix -Upper Triangular Matrix . . . . . . . -Lower Triangular Matrix

2. Classification

   • Inverse & transporse
     • Is determined by rows for the columns. If A is a matrix, then the transpose of a matrix is represented by A^(T).
     • For every m × n square matrix, there exists an inverse matrix. If A is the square matrix then A^(-1) is the inverse of matrix A

3. The determinant, works to solve a system of linear equations and to find the inverse of a matrix.
