Error when run koppen.m function

I am new to matlab code. i want to run koppen.m function in matlab and i have prepared precipitation data, temperature data and loation data . while running function it throw me an error .i confused with input data whether i prepare data is right or wrong . i will attach file with error and input data .

 for isite=1:size(temp,2)

At least one END is missing. The statement beginning here does not have a matching end.

    %%%
    %months comprised in summer and winter in each hemisphere
    if loc(isite,2) >= 0    %northern hemisphere
        summ=4:9;
        win=[1 2 3 10 11 12];
    else      %southern hemisphere
        summ=[1 2 3 10 11 12];
        win=4:9;
    end
    tann=nanmean(temp(:,isite));
    tmin=nanmin(temp(:,isite));
    tmax=nanmax(temp(:,isite));
    %%%
    pann=sum(precip(:,isite));
    ps=sum(precip(summ,isite));


    
    
    error: Index in position 1 exceeds array bounds. Index must not exceed 2.

Error in classKoppen>Koppen (line 79) ps=nansum(precip(summ,isite));

Hi Manikandan,

As per my understanding you are getting an "index exceeds array bounds" error. I assume that the logic of your code works perfectly fine and there is some issue in the indexing. You may go through a similar answer for debugging such a case:

I hope this helps!
