How do I put elements from one matrix into separate matrices using a loop?

I have a single matrix that contains the locations of pixels that burned within a geological boundary in a single file, organized by day of the year and longitude. I want to break this up into several matrices containing all of the row information from the first matrix, but contains only pixels that burned on a single day in one location. How can I seperate this large matrix into several matrices using a loop to compare the day of the year and longitude?

You can use functions like ismember. You can also use logical indexing. The best would be ismember. Read about the function.
