r = @(i) omega * beta * log2(1 + P(i)*gamma(i) / sum( P(1:i-1) .* gamma(i) + omega) )
It is not entirely clear to me whether the omega is included in the summation term or not.

Ok. I have used that command in my code
P=sort(B)
G=sort(A,'descend')
for i =1:size(P,1)
r = @(i) Bmax*log2(1+(P(i).*G(i))/((sum(P(1:i-1)).*G(i))+noise))
end
If I run the code I am getting
r =
@(i)Bmax*log2(1+(P(i).*G(i))/((sum(P(1:i-1)).*G(i))+noise))
r =
@(i)Bmax*log2(1+(P(i).*G(i))/((sum(P(1:i-1)).*G(i))+noise))
r =
@(i)Bmax*log2(1+(P(i).*G(i))/((sum(P(1:i-1)).*G(i))+noise))
Could you please tell me how can the values of P and G matrix can be substituted in r.

A particle moves with position function
s=t^4−4t^3−20t^3+20t,t≥0
a) At what time does the particle ha a velocity of 20 m/s?
b) At what time is the acceleration 0? What is the significance of this value t?

This is not an Answer to jaah navi's question. You should create your own Question. But first read Ask
