Function handles in MATLAB - Mini Project: Build & Apply

Using Function Handles in MATLAB

📖 Scenario: You are working on a simple calculator program in MATLAB. You want to use function handles to store different operations like addition and multiplication, so you can call them easily later.

🎯 Goal: Build a MATLAB script that creates function handles for addition and multiplication, then uses them to calculate results.

📋 What You'll Learn

Create function handles for addition and multiplication

Use the function handles to calculate the sum and product of two numbers

Print the results

💡 Why This Matters

🌍 Real World

Function handles let you store and pass around operations easily, useful in calculators, data processing, and callbacks.

💼 Career

Understanding function handles is important for MATLAB programming jobs in engineering, data analysis, and scientific computing.

1

Create two variables with numbers

Create two variables called a and b with values 5 and 3 respectively.

MATLAB

% Create variables a and b with values 5 and 3
% Your code here

Need a hint?

Use the assignment operator = to set the values.

2

Create function handles for addition and multiplication

Create a function handle called addFunc for addition and another called mulFunc for multiplication using anonymous functions.

MATLAB

a = 5;
b = 3;
% Create function handles addFunc and mulFunc
% Your code here

Need a hint?

Use the syntax @(x,y) x + y for addition and similarly for multiplication.

3

Use the function handles to calculate results

Use the function handles addFunc and mulFunc to calculate the sum and product of a and b. Store the results in variables sumResult and productResult.

MATLAB

a = 5;
b = 3;
addFunc = @(x,y) x + y;
mulFunc = @(x,y) x * y;
% Calculate sumResult and productResult using function handles
% Your code here

Need a hint?

Call the function handles like regular functions with (a,b).

4

Print the results

Print the values of sumResult and productResult using disp with descriptive text.

MATLAB

a = 5;
b = 3;
addFunc = @(x,y) x + y;
mulFunc = @(x,y) x * y;
sumResult = addFunc(a,b);
productResult = mulFunc(a,b);
% Print sumResult and productResult with descriptive text
% Your code here

Need a hint?

Use disp(['Sum: ', num2str(sumResult)]) to print the sum.
