MATLAB: How to output your numbers into an array

arrayoutput arrayoutput into arrayprime number

I am taking private tuition for Matlab programming and I am stumped on this –
I wrote a program to find the prime numbers between X and Y. I need to output the prime numbers into an array… but how? Can you edit this program and show me how?
x = input ('Enter start no.: ')
y = input ('Enter end no.: ')
for n = x:y
    count = 0;
    for b = 1:n
        if rem(n,b)== 0
            count = count+1;
        end
    end
    if count == 2
        display(n);
    end
end

Best Answer

x = input('Enter start no.: ')
y = input('Enter end no.: ')
prim=[];
for n = x:y
  count = 0;
  for b = 1:n
      if rem(n,b)== 0
          count = count+1;
      end
  end
  if count == 2
      prim(end+1)=n;
  end
end
display(prim)
%or
x = input('Enter start no.: ')
y = input('Enter end no.: ')
prim=[];
for n = x:y
  if numel(find(~rem(n,2:n)))==1
      prim(end+1)=n;
  end
end
display(prim)
