Looks peculiar orientation as doesn't keep the similarly-valued variables together, but per your request--
AAA_010 AAA_002 AAA_143 AAA_123
_______ _______ _______ _______
145.65 145.66 145.64 145.82
18.81 18.73 18.77 17.59
29.06 29.1 29.02 29.27
28.48 28.52 28.49 28.94
Also, those names are going to be very difficult to use in being only distinguished by the trailing digits unless it is intended that names be automatically generated and/or the column positions are known. Of course, with 600 variables, having individual names/variables is going to be an issue in and of itself.
I'd suggest probably keeping the array structure and using the vector operations possible in Matlab will be more fruitful way to process your data but we're not given any indications of what intend to do next.
