Defining Local Functions

1. Create a Script: Start by creating a new script or live script in MATLAB. You can do this by selecting "New Script" from the Home tab.
2. Add Code: Write your main script code as you normally would. After your main code, you can define local functions. Each local function must start with its own function keyword and can be placed anywhere in the script, but traditionally, they are placed at the end of the script.

3. Function Syntax: The syntax for defining a local function is as follows:

function output = functionName(input)
% Function code here
end

function meanValue = myMean(array)
meanValue = sum(array) / length(array);
end

Example of a Script with Local Functions

% Main script code
data = [^1^];
meanValue = myMean(data);
medianValue = myMedian(data);
% Display results
disp(['Mean: ', num2str(meanValue)]);
disp(['Median: ', num2str(medianValue)]);
% Local function to calculate mean
function meanValue = myMean(array)
meanValue = sum(array) / length(array);
end
% Local function to calculate median
function medianValue = myMedian(array)
sortedArray = sort(array);
n = length(sortedArray);
if mod(n, 2) == 0
medianValue = (sortedArray(n/2) + sortedArray(n/2 + 1)) / 2;
else
medianValue = sortedArray((n + 1) / 2);
end
end

Benefits of Using Functions in Scripts

• Reusability: Local functions allow you to reuse code within the same script without needing to create separate function files.

  2
• Organization: Functions help organize your code into logical segments, making it easier to read and maintain.

  1
• Modularity: By breaking down complex scripts into smaller functions, you can improve the clarity and structure of your code.
