q=1:t-1;
throughput_E = Bmax*log2(1+p_fix(t)*gamma(t)/symsum(p_fix(q,1,t-1).*gamma(t)))
If i run the code i am getting Subscript indices must either be real positive integers or logicals.
Error in throughput_E =Bmax*log2(1+p_fix(t)*gamma(t)/symsum(p_fix(q,1,t-1).*gamma(t)))

This kind of error is appearing may be because of the q value defined. If the q value at t-1 becomes negative or zero and the function is unable to take negative value. Hope it gives some help. Thanks.

You have redefined a function by an array. Maybe this is "gamma", "log2", "p_fix" or "symsum". Without seeing the complete code, it is impossible to guess, which of these symbols cause the problem. But you can use the debugger to find this information. Please debug your code by your own before you ask the forum.
