A script that writes all even numbers from 1 to 100

I want to write a script that prints all even numbers at the range [1, 100] On one hand how would I use the while loop and on the other how would I use the for loop for this script?

doc for
doc while

I know this is a help forum, but come on, put some effort in at least to working out how to do it yourself. In this case you need neither a for loop nor a while loop, but you seem to want to know how to use them so those are the help paages.

In addition to

   doc for
   doc while

please try

   doc linspace

and

   doc colon

and fprintf().

Here is a beginning using while, :

 N=100;
 n=1;
 c=1;
 while n<N
  if mod(n,2)==0
    E(c)=n;c=c+1;
 end
 n=n+1;
 end

You can use fprintf on vector E to print the even values.

a fast way is better, using a vector, you cancel the value that have residue when you divide by 2:

      E=1:100;
      E(mod(E,2)~=0)=[]
