MATLAB: Conditional statements and while loop

Question

Hi,

I have the following while loop

while (dif1 > tol) &&  (dif2 > tol) && (dif3 > tol)
procedure 
end

I want all the conditions to be simultaneously satisfied. However, when I execute the code, the second condition dif2 > tol is not satisfied although the algorithm stops.

what I am doing wrong here ?

Answer 1

while (dif1 > tol) ||  (dif2 > tol) || (dif3 > tol)

should work if you want to carry on until all are false.
