They are just variables when used like this:
[m,n,p] = size(rand(2,3,4))
m holds the first dimension (the number of rows)
n holds the second dimension (the number of columns)
p holds the third dimension of the array, think about it like the number of pages

just variables, no particular meaning, use the variables you like the most

Historical habit in mathematics, just like using the beginning of the alphabet to represent constants and using the end of the alphabet to represent variables.

No. The programming language doesn't care which variable name you use, but you will lose efficiency from people reading your code and attempting to figure out what your names mean. If you are going to use non-traditional names, use names that are self-explanatory.
