What is MATLAB?
MATLAB, short for “Matrix Laboratory,” is a specialized programming platform used primarily for numerical computing. Why such a name? Because it deals with matrices. Developed by MathWorks, MATLAB is favored by engineers and scientists for its powerful capabilities in matrix manipulations, data plotting, algorithm implementation, and interface creation with other programming languages.
The core of MATLAB is its language, which is specifically designed to work with matrix and array mathematics directly. This makes it particularly effective for tasks that involve complex mathematical computations like data analysis, development of algorithms, and modeling of systems and processes. MATLAB also supports various toolboxes which are extensions that provide additional functions for specific types of tasks.

Coding with MATLAB: Sample Code
You know what MATLAB is and how it’s used. Now let’s learn how to use it. We are going to create a simple MATLAB sample code that calculates the factorial of a number using a function.:
function result = calculateFactorial(n)
% This function calculates the factorial of a positive integer n.
% The factorial of n (denoted as n!) is the product of all positive integers up to n.
% Check if the input is a positive integer
if n < 0 || mod(n, 1) ~= 0
error(‘Input must be a non-negative integer’);
end
% Initialize the result to 1 (since the factorial of 0 is 1)
result = 1;
% Loop from 1 to n to calculate the factorial
for i = 1:n
result = result * i;
end
end
How to Use MATLAB Code?
- Copy the Code: Copy the above code into a new file in MATLAB. Save the file with the name calculateFactorial.m. This name must match the function name for MATLAB to recognize it correctly.
- Call the Function: You can call this function from the Command Window or from another script. For example:
num = 5;
fact_result = calculateFactorial(num);
disp([‘The factorial of ‘, num2str(num), ‘ is ‘, num2str(fact_result)]);
- Test Different Values: You can test this function with different values by changing the value of num and rerunning the script.
