To do this, click the "Upload" button under the HOME tab, then navigate to and select the data.csv file.

Import the data into the MATLAB Workspace

In the Command Window, enter the following (hint: use copy and paste) after the >> prompt:

mystery = importdata('data.csv')

Then click Enter (or Return) on your keyboard.

This will save the data.csv file under the variable name mystery.

Show the image hidden within the CSV file

In the Command Window, enter the following command after the >> prompt:

Then click Enter (or Return) on your keyboard.

imshow() is a function in MATLAB which will show an image. This function takes one argument (piece of information): the image, which in this case is mystery.
