It sounds as if your variable named "cellsize" is of type char.

It is legal to have a statement such as

for i = 'J':'*'

and it is legal to have

for i = 54:112

but it is not legal to have a number on one side of the colon and a character on the other side of the colon.

I think it more likely than not that what you are trying to do is completely wrong, but in the meanwhile you can get around the immediate problem by using

for i = char(1):cellsize
