How can I write this code in matlab and have it run? ( all variables have been defined but it keeps giving me an error on this line)

Hi Adam Sabah,
when I run your code I get this error message:
ue = 1-4*sin((3*pi*x)/(2*L))*exp(-tmax(A/B))+4*sin((7*pi*x)/(2*L))*exp(-tmax(C/B));
!! Subscript indices must either be real positive integers or logicals.
Matlab tries to evaluate the expressions "tmax(A/B)" and "tmax(C/B)" as vector tmax at index A/B and C/B respectively. Since A/B and C/B are real numbers and not integers Matlab cannot determine the indices, despite the fact that tmax is scalar, and defined as 25. I assume you are missing multiplication signs.
