MATLAB: Loop until condition met

Vo = [30 15 13 10];% initial V old to calc Re and f.
MaxIter=1e10;
%






Cntr=0;
while true
Cntr=Cntr+1;
%
Re1 = (D(1).*Vo(1)) / nu;
%
Re2 = (D(2).*Vo(2)) / nu;
%
Re3 = (D(3).*Vo(3)) / nu; 
%
Re4 = (D(4).*Vo(4)) / nu;
%
A = [Matrix];
b = [Matrix];
Vn = A\b;% solves four unknowns at A\b
%
for i = 1:4
Va(i) = (alpha * Vn(i)) + ((1-alpha) * Vo(i));
end
if all(abs(Va-Vn(1:4))<1e-10) && all(abs(Va-Vo)<1e-10) 
   break;
end
if Cntr==MaxIter  % add this to avoid being stuck if there is no solution.
   break;
end  
Vo=Va;

MATLAB: Loop iteration with condition met

Tol=1.5;ma=10;
t=[1 2];
B=[];
 for a=1:ma
     x=rand();
     result=sum(x*t);
     while result>Tol || result<0.5
       x=rand()
       result=sum(x*t);
       B(a)=result;
     end
 end
 B
