MATLAB: Can someone help me with the if statements in the function

Question

I have written this function for a homework assignment, Basically finding heronian isosceles triangles for a given Perimeter. My if statements

if ((b>= 2*a)) && ((b<=0));
      continue
      end
if IntTestA == 0
          a=0; b=0; A=0;
          continue
end

are not working properly I was wondering if someone could explain to me why.

Answer 1

I quickly see three issues:

1. a is always positive so b can never be both positive (>=2*a) and negative (<= 0).
2. for A = sqrt(...) is a loop over a single value
3. setting the iterator in a loop (a=0) does not effect the loop. See this example

for k=1:5
  disp(k)
  k = 5 ;
  disp(k)
end
