Cell array creation in MATLAB - Mini Project: Build & Apply

Cell array creation

📖 Scenario: You are organizing a small collection of different types of data about fruits. You want to store their names, colors, and average weights together in a flexible container.

🎯 Goal: Create a cell array in MATLAB that holds the fruit names, their colors, and their average weights. Then, display the cell array.

📋 What You'll Learn

Create a cell array called fruits with exactly three rows and two columns.

The first row should contain the fruit names: 'Apple' and 'Banana'.

The second row should contain the colors: 'Red' and 'Yellow'.

The third row should contain the average weights in grams: 150 and 120.

Display the entire fruits cell array using disp.

💡 Why This Matters

🌍 Real World

Cell arrays let you store mixed data types together, like names, numbers, and descriptions, which is common in data analysis and reporting.

💼 Career

Knowing how to create and manipulate cell arrays is useful for engineers and scientists who work with diverse datasets in MATLAB.

1

Create the cell array fruits

Create a cell array called fruits with three rows and two columns. The first row should have 'Apple' and 'Banana'.

MATLAB

% Create the cell array fruits with fruit names in the first row
% Your code here

Need a hint?

Use curly braces {} to create a cell array. Separate rows with semicolons ;.

2

Add colors to the second row

Add the colors 'Red' and 'Yellow' to the second row of the fruits cell array.

MATLAB

fruits = {'Apple', 'Banana'; '', '' ; '', ''};
% Add colors to the second row
% Your code here

Need a hint?

Replace the empty strings in the second row with the color names.

3

Add average weights to the third row

Add the average weights 150 and 120 to the third row of the fruits cell array.

MATLAB

fruits = {'Apple', 'Banana'; 'Red', 'Yellow' ; '', ''};
% Add average weights to the third row
% Your code here

Need a hint?

Replace the empty strings in the third row with the numeric weights.

4

Display the fruits cell array

Use disp(fruits) to display the entire fruits cell array.

MATLAB

fruits = {'Apple', 'Banana'; 'Red', 'Yellow' ; 150, 120};
% Display the fruits cell array
% Your code here

Need a hint?

Use disp to show the contents of the cell array in the command window.
