Introduction to Matrices and Matrix Operations - Linear Algebra

In mathematics, a matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.

The size of a matrix is defined by the number of rows and columns it contains. There is no limit to the numbers of rows and columns a matrix (in the usual sense) can have as long as they are positive integers. A matrix with m rows and n columns is called an m × n matrix, or m-by-n matrix, while m and n are called its dimensions.
In this video we will learn what is a matrix, matrix notation, how to determine the order of a matrix, what are matrix elements and also we learn about the addition and subtraction of matrices and about the trace of a matrix and much much more...
