Hi all. I am trying to use while-loop to determine when the cumulative rainfall for a particular month exceeds 8 mm. I have attached the file that I imported for my data. Also, this is the code that I used, but didn't work. Any help would be highly appreciated !
Testdata = importfile2('Test_data.csv', 2, 32);
%Parameters
RF=Testdata(1:31,4);
%Variables
D_var=0; % day
RF_tot = 0; % Rainfall total
%Condition
%RF_tot <=7
while RF_tot<=8
RF_tot=RF_tot+RF
D_var=D_var+1
end

while RF_tot<=8 && D_var <= 30
D_var=D_var+1
RF_tot=RF_tot+RF(D_var)
end
Best wishes
Torsten.

As far as I understood your code, array element RF(D_var) contains the rainfall at day D_var of a certain month. If this is the case, these values RF(1),RF(2),...,RF(31) have to be added together to get the total rainfall of the month. The condition to stop is that the total rainfall up to day "D_var" exceeds 8 mm.
Thus you could equivalently do
RF_total = 0.0;
for D_var = 1:31
RF_total = RF_total + RF(D_var);
if RF_total > 8
break
end
end

@Torsten Many thanks. This makes perfect sense. Much appreciated.
