Hi all,

I'm practicing to create exponential random numbers. The following is my code. I can only run it once. When I tried to run the second time, it appeared the error message, "Indexing cannot yield multiple results". I can run my code again if I use clear all. How can I solve it? Thank you!

function [exprand,average,std_dev]=exprand(m,n,h,mu)
exprand=zeros(m,n,h);
exprand=-mu*log(1-rand(m,n,h));
average=sum(sum(exprand))/(m*n);
std_dev=sqrt(sum(sum((exprand-average).^2))/(m*n));

You have an output variable named the same as the function. That's a
poor idea.
