Using Matrices in Real Life

In real life Matrices can be used in encryption, encryption is the process of transforming important information using related algorithm to make it unreadable or inaccessible to another person except those possessing special information. When a programmer encrypts or codes a message, he can use matrices and their inverse.

In real life Matrices are also used in graphs in scientific studies. Data organized in columns and rows can be represented as matrices. Matrices are used for representing real word data. We can understand it by following example:

Color of eyes in a class of students:

 Gender Brown eyes Blue eyes Black eyes Green eyes Male 27 18 57 15 Female 19 14 49 13

Table above expressed as Matrix:

• Each row represents Male/Female eye color (row first for male and row second for female).
• Each column represents a different eye color (column first represent Brown eyes, second Blue eyes, third Black eyes and fourth for Green eyes).

Matrices also used in schools for representing grades and attendance. A class can be modeled as a matrix where rows are student and columns show grades for assignment.

 Roll no of student Assignment 1 Assignment 2 Assignment 3 1 A+ B+ A 2 A B+ B 3 B+ A+ A+ 4 A++ A+ A+

Using Matrices in real life we can calculate domestic product in economics and matrices also helps in calculations for producing goods efficiently. Matrices also use scientific studies in many important fields like Home work, Sport, Recreation and Sports. Matrices are also used in organizations to record data from experiments if it includes Numbers.

Matrices are also sometimes used in computer animation and graphics like transforming images through rotation, reflection and translation.
