Question

define matrix and give example? ​

Answer 1

Step-by-step explanation:

A matrix is a collection of numbers arranged into a fixed number of rows and columns. Usually the numbers are real numbers. In general, matrices can contain complex numbers but we won't see those here.

Here is an example of a matrix with three rows and three columns: The top row is row 1.

Example: E is a row matrix of order 1 × 1.

Example: B is a row matrix of order 1 × 3. A

Answer 2

Answer:

A matrix is a collection of numbers arranged into a fixed number of rows and columns. Usually the numbers are real numbers. In general, matrices can contain complex numbers but we won't see those here. Here is an example of a matrix with three rows and three columns: The top row is row

1. The leftmost column is column 1. This matrix is a 3x3 matrix because it has three rows and three columns. In describing matrices, the format is:

rows X columns

Each number that makes up a matrix is called an element of the matrix. The elements in a matrix have specific locations.

The upper left corner of the matrix is row 1 column 1. In the above matrix the element at row 1 col 1 is the value 1. The element at row 2 column 3 is the value 4.6.

Forthe dimension of the matrix below is 2 × 3 (read "two by three"), because there are two rows and three columns:

An m × n matrix: the m rows are horizontal and the n columns are vertical. Each element of a matrix is
