The document serves as an introduction to MATLAB, covering its basic functionalities such as matrix operations, plotting, and creating systems. It includes MATLAB commands for performing various tasks and demonstrates how to manipulate images. The content is structured into sessions, each focusing on different capabilities of MATLAB.
![Session 1: Jan 31, 2017 | BASICS
Creating a matrix and
performing following functions:
Addition
Subtraction
Multiplication
Division
MATLAB Command:
A=[1 2 3; 4 5 6; 7 8 9];
B=[1 3 5;7 9 11; 13 15 17];
