I should make an iterative cylce, yet when trying to run it gives me this error
Array indices must be positive integers or logical values.
for i= linspace(0.0001,0.0009,1000)
Fm= (0.25).*(((log((2.7*10^-5)+(2.51.*((Rey.*sqrt(i).^-1))))).^-1).*((log((2.7*10^-5)+(2.51.*((Rey.*sqrt(i).^-1)))))).^-1);
if Fm(i)-Fm(i+1)<= abs(10^-6)
break
end
end

i= linspace(0.0001,0.0009,1000)
%.................^ ...........^............
Array indices must be non zero positive integer
like
linspace(1,1,1000)
Aprat from the above issue there is undefined function or variable 'Rey'. Ensure that it is there in your complete code.

Probably you want (no loops needed):
ii = linspace(0.0001,0.0009,1000);
Fm = (0.25).*(((log((2.7*10^-5)+...
(2.51.*((Rey.*sqrt(ii).^-1))))).^-1).*((log((2.7*10^-5)...
+(2.51.*((Rey.*sqrt(ii).^-1)))))).^-1);
First_encounter = find(abs(Fm(1:end-1)...
-Fm(2:end))<= 1e-6,1,'first')
