How to show conditions (pop out search vs conjunction search with four levels (set size= 4,8, 12,16)

Attempting to do project 6.4 in Matlab for Neuroscientist but do not understand how to write a code to show these two conditions. This is from chapter 6 in the book.

This appears to relate to https://www.mathworks.com/academia/books/matlab-for-neuroscientists-wallisch.html and in particular "Chapter 6 - Collecting Reaction Times I: Visual Search and Pop Out"

Unfortunately it appears that that book currently costs about $US66 in electronic form (over $US100 in print + ebook bundle), so most of us do not have access to it.

I highly doubt anyone will read a chapter in order to answer a question (especially when reading from a series of images). It will be more helpful to us and, more importantly, to you, if you frame a self-contained question that focuses on where you're stuck.

Framing a detailed question that makes clear what kind of data you're working with, what you've tried, why it's not working, and where exactly you're stuck, is an exercise that will help the questioner tramendously.

I deleted the copyrighted material. Access to the book is sold chapter by chapter, so it is not plausible to think that the authors wished to make a chapter available for free.

You can use questdlg() or menu() to get the user to select between discrete choices.

Or you can use uicontrol('style', 'popup') or uicontrol('style', 'listbox') along with setting Callback properties for those to detect when the user has made a choice. As a beginner, GUIDE can help with that (though GUIDE has a lot of limitations.)

Or you can use the newer App Designer along with uilistbox() or uidropdown()
