how to write matlab code for this equation?

sa=0;
for a=1:K
    sa=sa+log2(1+r(a)/U);
end
display(sa)
as = 1*10^-10;
bs= 1*10^-5;
rs = (bs-as).*rand(K,1) + as;
pow=0;
for d=1:K
    pow=pow+((Ptot(d)/U)+rs(d));
end
display(pow)
ptc=1*10^-3;
par=pow+ptc
nreee=sa/par

Which problem do you have with the posted code?

how to take arg max for the equation i attached in my question

[Walter Roberson]

fmincon the negative of the function to search for the argument that maximizes the function over a continuous domain. Over a discrete domain... Try them all.

please refer above equation i have attached ,i wrote code for that equation ,for that equation how to i take arg max there P is a power allocation vector P=[p1,p2,p3.....pk]T T is a transpose,please reply it fast .

[Walter Roberson]

You are using a discrete domain of pk. To find the pk that maximizes the equation, try them all, and use the two-output form of max() to identify the index that returns the largest value.
