Leo S submitted a Comment to Problem 23. Finding Perfect Squares I solved it with 2 for-loops, 1 function, 1 if-condition.
It works, but there are more efficient ways apparently

Leo S submitted a Comment to Problem 14. Find the numeric mean of the prime numbers in a matrix. What is wrong with
a = find( isprime( in))
out = mean( in( a)) ?
It works perfectly in my own MATLAB environment

Leo S submitted a Comment to Solution 3745618 Eh okay. I dislike this problem.
First, I used a "for loop", but the results were often not logical/ reliable. I than used
a = 1 : 1 : length(x) - 1;
if all( x(a) < x(a + 1))
tf = true;
end
and it worked. But why can't I use a "for loop"?! I feel like I did not learn anything from this
