Matlab loops for a function

I am trying to make a loop to redo a Matlab function 1000 times. Here's the program

d = unifrnd (0,10,[10,1]);
c = d.^(-2);
a = round(unifrnd(0,1,[1,10]);
e = a*c
btotal = e+1
SIR = 1/btotal

What I want is to iterate this function 1000 times, each time the value of SIR will vary due to the random number generated. For every iteration, I want the value of SIR to be added together (summed up), and in the end of the 1000th iteration, find the average SIR(mean).

Thanks for the help

The code below implements what you described:

genSIR.m

function SIR = genSIR()
    d = unifrnd (0,10,[10,1]);
    c = d.^(-2);
    a = round(unifrnd(0,1,[1,10]));
    e = a*c;
    btotal = e+1;
    SIR = 1/btotal;
end

main program

N = 1000;
SIR = zeros(N,1);
for i=1:N
    SIR(i) = genSIR();
end
s = sum(SIR)
m = mean(SIR)

although your function could be simplified...
