Question 1. What is MATLAB?
MATLAB, short for Matrix Laboratory, is a high-performance programming language and environment primarily used for numerical computing, data analysis, and visualization.
Example:
disp('Hello, MATLAB!');
Question 2. Explain the difference between a script and a function in MATLAB.
In MATLAB, a script is a collection of MATLAB commands saved in a file with a '.m' extension, whereas a function is a set of MATLAB commands grouped together to perform a specific task, and it can accept input arguments and return output.

Example:
data = csvread('filename.csv');
Question 4. Explain the use of the 'plot' function in MATLAB.
The 'plot' function in MATLAB is used to create 2D line plots. It is commonly used to visualize data and relationships between variables.
Example:
x = linspace(0, 2*pi, 100);
y = sin(x);
plot(x, y);
Question 5. What is the purpose of the 'imshow' function in MATLAB?
