Say I have a given array:
array=[4,5,6,7,8;4,6,9,8,1;3,7,4,5,9;6,7,8,1,4]
array = 4×5
4 5 6 7 8 4 6 9 8 1 3 7 4 5 9 6 7 8 1 4
I'm trying to find the location in the array where the first two numbers in the row are equal to 4 and 5. How can I sort the array to get only the row that matches these restrictions?

Here's one way:
array = [4,5,6,7,8;4,6,9,8,1;3,7,4,5,9;6,7,8,1,4];
matchedrows = find(all(array(:,1:2) == [4 5],2))
matchedrows = 1
