Is it possible to see what data type the variables are saved as and how many bites they are?

Thx. If I do this for the different variables in the two files. It seems like the variables have the same size. ?
if true
Dat18 size bytes size of 1 variable class
dato 17615 140920 8 double File size: 14,8 mb
files 17615 3376212 191,6668748 cell
mappe 17615 2254720 128 cell
tog 17615 140920 8 double
Dat2017
dato 24454 195632 8 double File size: 206 kb
files 24454 4688868 191,7423734 cell
mappe 24454 3130112 128 cell

If I look at the bytes Dat2017 should be bigger than Dat18. But it isn't. So why is Dat18 so much bigger?

I used the function save.
: save(strcat(datainfo,year,'.mat'), 'fil', 'tog', 'dato', 'mappe')
