Question about random numbers and rejecting

10 views (last 30 days)
Hi there, I'm new to matlab. I'm trying to make a function, where you input a,b, and c generates a random integer from a to b and the function rejects the c value. I tried
function r =randnum_reject(a,b,c)
r=randi([a,b]);
if r==c
?????
end
end
I don't know what to do after the if statement. Any help? Thanks EXAMPLE: Like say I type randnum_reject(1,10,2), and my function will output a random number from 1 to 10, but NOT 2.

function r = randnum_reject(a,b,c)
% Rudimental check
if isequal(a,b,c)
return
end
r = c;
while r == c
r = randi([a b]);
end
end
You might wanna improve input checking to avoid:
randnum_reject(0,0,0)
which will get you into an infinite loop.
