Matrix Operations
Akopọ
A matrix is a rectangular grid of numbers that lets you store and manipulate a whole table of data, such as a set of sports results or a system of coordinates, using a single algebraic object. Once the rules for combining matrices are fixed, matrices become a compact way to represent information that would otherwise take rows of separate equations.
This topic covers representing data as a matrix, adding and multiplying matrices (including the surprising fact that order matters), multiplying by a scalar, the identity and zero matrices, and finding the determinant and inverse of a 2 by 2 matrix.
Awọn Afojusun
- Represent data by a matrix
- Perform addition and multiplication of matrices of order not more than 3 x 3
- Multiply a matrix by a scalar
- Understand and use unit (identity) matrix and zero (null) matrix of order not more than 3 x 3
- Find determinants and inverses of non-singular 2 x 2 matrices
