how To change this C++ code to matlab code ?

#include math.h

double AttackerSuccessProbability(double q, int z)

{

double p = 1.0 - q;

double lambda = z * (q / p);

double sum = 1.0;

int i, k;

for (k = 0; k <= z; k++)

{

double poisson = exp(-lambda);

for (i = 1; i <= k; i++)

poisson *= lambda / i;

sum -= poisson * (1 - pow(q / p, z - k));

}

return sum;

}

Answer 1

[Birdman]

function y=AttackerSuccessProbability(q,z)
p=1-q;
lambda=z*q/p;
sum=1;
for k=0:z
    poisson=exp(-lambda);
    for i=1:k
        poisson=poisson*lambda/i;
    end
    sum=sum-poisson*(1-((q/p).^(z-k)));
end
y=sum;
end

This one works.
