A matrix is a rectangular array of numbers. It is represented by a capital letter, such as A. Each element of the matrix is represented by a lowercase letter, such as a11.
Matrices can be added together, subtracted from each other, multiplied by scalars (numbers), and manipulated in various ways. They have many applications in various fields such as statistics, physics, engineering, and computer science.
Examples:
A = | 2 3 4 |
A = | 1 2 3 |
A = | 4 5 6 |
Matrices can be used to represent linear transformations, which are operations that change the position of points in a coordinate system.
They are also used to model physical systems, such as systems of equations and differential equations
