MATLAB: A function to find prime number

Question

Hello,

I wrote a function to find a prime number and would like to run it to find all prime numbers up to 100 from my starting point. However, I get an error saying "too many output arguments".

Here is what I have…

function isPrime(number)
tf=isprime(number);
if tf==true
    disp(number)
end
end
starting_point=input("Enter your number: ");
while starting_point<100
    disp(isPrime(starting_point))
    starting_point=starting_point+1;
end

I would really appreciate if anyone can help me with this problem….

Your function doesn't return anything, so when you try to use its output you get an error. Change this:

function isPrime(number)

to this

function tf = isPrime(number)
