I am wanting to create a code that will read from an Excel file (I have attached an example below). I want the total number of students, check-in types to be sorted, and for the date and time to be sorted. I am very new to Matlab and this would help make my job much easier!
[~,~,rawData] = xlsread('matlabproject.xlsx');

mask = ismember(rawData(:,3), {'Student Check-In (DB)', 'Student Check-Out (DB)'});
student_subset = rawData(mask,:);
Now you can start processing to find the unique column 2 (names) in student_subset and so on.

Hi Walter,
Thank you so much! It works! Would you possibly know how to sort the date and time or direct me to some reasources to figure it out?
Thanks,

Hi
You may find a way to sort date and time from this link below:

May be you need to change the format in "datenum"

If you switch from xlsread() to readtable() then the first variable in the table will automatically be created as datetime() objects
