MATLAB does not have implicit multiplication between adjacent values or variables. You need to write the multiplication explicitly:
a = T .* 247.8./((T-273)+68.12963)
^^ You need this!
I also fixed the unmatched parentheses.

If you just did
a=(T);
then that should work, but if you do
a=(T) 247.8./((T-273)+68.12963))
then there is no operator between the T) and the 247 and that causes a problem. Computer programming is not like writing or textbooks, where you can just leave out the multiplication symbol. If you want to multiply two things, like T and 2, or T and A, then you must put either a matrix multiplication operator, T*A, or an element-by-element operator T.*A.
