MATLAB: How to go back to check condition again after the if-else statement

if else

This is my coding,
    cond=exp(z(2)*(1-z(1)))-(1/z(3));
    if cond<0
        h=@test;
        znew=simulannealbnd(h,z,[0 0 0],[1.0 10.0 1.0],options)
    else
        r1 = a1 + (b1-a1).*rand(1,1);
        r2=  a2 + (b2-a2).*rand(1,1);
        r3=  a3 + (b3-a3).*rand(1,1);
        z=[r1 r2 r3];
    end
After getting the z=[r1 r2 r3], i want to go back to check the condition again. How to write the code?

Best Answer

test=0;
while test==0
cond=exp(z(2)*(1-z(1)))-(1/z(3));
if cond<0
  h=@test;
  znew=simulannealbnd(h,z,[0 0 0],[1.0 10.0 1.0],options)
  test=1;
else
  r1 = a1 + (b1-a1).*rand(1,1);
  r2=  a2 + (b2-a2).*rand(1,1);
  r3=  a3 + (b3-a3).*rand(1,1);
  z=[r1 r2 r3];
  test=0;
end
end
