for the above equation i need to partially differentiate z wrt A() and T() . how do i include the summation in matlab code.
Thank you in advance

And you want to do this symbolically? Looks to me that this would be a possibility:
1. create a variable for each summation index. You can do this e.g. using the syntax
a_vec = sym('a',1:J);
2. define the term z = sum(....)
3. differentiate w.r.t each variable, either in a loop, or in vector form using the jacobian function. See here:
