How to combine 2 two-dimensional arrays into 3-D array with two pages?

Well, I have 2 5x4 arrays of data of test scores of 2 years. I am not sure how to combine them together to get a 3-D array of the data. I know how to create a 3-D array of just one but not combining the two of them. Any help would be appreciated. The arrays are called year1 and year2, combine to create 3-D array for testdata. Would it just be as simple as testdata = {year1,year2} ??

testdata = cat(3, year1, year2);
