Hi Samuel Maliva,
Reducing or eliminating code duplication in MATLAB can make the code cleaner, more readable, and easier to maintain. Here are some approaches to achieve this:
- Use Functions and Scripts
Modularize repeated logic into functions (with inputs and outputs). Use scripts for repetitive setup/config tasks (but functions are preferable whenever possible).
% Example: Repeated calculation
function result = computeArea(radius)
result = pi * radius^2;
end
% Usage
area1 = computeArea(5);
2. Leverage Loops
Instead of repeating similar operations, use loops to iterate over data or parameters.
% Example: Avoid duplicating similar operations
radii = [5, 10, 15];
areas = zeros(size(radii));
for i = 1:length(radii)
areas(i) = pi * radii(i)^2;
end
3. Utilize Vectorization
MATLAB is optimized for vectorized operations, which can replace repetitive code with concise, efficient expressions.
% Example: Vectorized computation
radii = [5, 10, 15];
areas = pi * radii.^2; % Compute areas for all radii in one line
4. Anonymous Functions
In MATLAB, an anonymous function is a one-line function that does not require a separate file. It is defined using the @ symbol and is particularly useful for simple operations or when passing functions as arguments.
% Example: Multiple Inputs Anonymous Function
add = @(a, b) a + b; result = add(3, 7); % Output: 10
5. Object-Oriented Programming (OOP)
Use MATLAB classes to encapsulate data and behavior. It is great for large projects with repeated patterns.
classdef Circle
properties
Radius
end
methods
function obj = Circle(r)
obj.Radius = r;
end
function a = area(obj)
a = pi * obj.Radius^2;
end
end
end
By combining these techniques, one can significantly reduce code duplication, improve readability, and enhance performance in MATLAB projects.

I hope this helps!
