    Unhappy MATLAB code to display prime numbers?

    Can you guys please help me with a MATLAB code, I need a simple program to display the prime numbers between 1 and 100. Please help as I am new to programming and I have to do it as an assignment.

    it has been a while since I have done MATLAB (and I did not do a whole lot in it but I will help you with the logic flow so you can figure it out) You cannot post questions on "how do I do this" for assignments, but you can ask for help on why things are not working... this pseudo code may help you
    int[] myNums = new int[100]
    totalprime =0
    while (i<=100){
      bool eval = true
      cnt = 0
      while(eval = true){
         for(int y=1; y<=i; y++)
         if(i%y != 0) eval = false
         else cnt++
         if (y==i) eval false
      if(cnt == 2) myNums[totalprime] = i
    i think that logic flow is correct... take a look at it and tell me if you can figure out what it is doing... a key to doing this is going to be modulus

    I code C hash-tag .Net
