Hi, for the following code:
n = 50000;
g = 0.3;
x = [];
for i=1:n
k = 0;
while unifrnd(0,1) < g
k = k + 1;
end
b = 0;
mynumber = 2;
for j = 1:k
switch mynumber
case 1
v = random(beta,3,3)
case 2
v = random(gam,5,5)
case 3
v = random(exp,3)
case 4
v = random(geo,0.2)
case 5
v = random(unif,0,5)
case 6
v = random(norm,0,1)
end
b = b + v;
end
if b ~= 0
x = [x, b];
end
end
I get the following error: Undefined function or variable 'gam'.
Error in test (line 21) v = random(gam,5,5)
why is that? Thanks

You can tell us what is the value of gam?

see, You hav to declare the variable 'gam' and others as global or local, then only you can call it..

But "gam" is just an already defined distribution in matlab...as "normrnd(.." since when has this decleration to be done? And where do I have to do it?
