Matlab 👩‍💻 Cell Arrays

This tutorial covers the use of cell arrays in MATLAB and Octave, demonstrating their flexibility in storing different data types such as strings and numbers. It includes examples of creating, manipulating, and accessing elements within cell arrays. The video also features activities like storing egg colors and recording data from a TC lab experiment, highlighting the practical applications of cell arrays in data management.

What is a key advantage of using cell arrays in MATLAB?

• They are easier to use than regular arrays.

• They can store different data types.

• They are faster than regular arrays.

• They can only store numbers.

Which of the following is NOT a valid element in a cell array?

• Function

• Number

• Array

• String

How can you replace an element in a cell array?

• Using the replace function

• Directly assigning a new value to the cell

• Using the swap function

• Using the delete function

What function is used in MATLAB to compare two strings?

• strcompare

• strcheck

• strcomp

• strcmp

In the activity, what is the purpose of the while loop?

• To continuously prompt for input until a condition is met

• To compare strings

• To iterate over a fixed number of times

• To replace elements in a cell array

What is the correct way to input a string in MATLAB?

• Using input() with a comma and 'string'

• Using input() with a comma and 'S'

• Using input() with a comma and 'char'

• Using input() without any additional parameters

What is the purpose of the cell to mat function?

• To add elements to a cell array

• To remove elements from a cell array

• To convert a cell array to a matrix

• Heater status

What is the purpose of using F printf in the lab experiment?

• To write data to a file

• To read data from a file

• To print data to the console

• To format data for display

What is a CSV file used for in the context of the lab experiment?

• To store images

• To store text data

• To store binary data

• To store structured data in a tabular format
