Index in position 1 exceeds array bounds.

Hello everyone,

I have been given a code where this portion is not letting me proceed right now.

I have not written the code, neither am I normally coding. I understood the concept of the error mentioned in title, but I do not understand where to apply it in the code and at wish point my array has been apparently defined over 1.

Here is the portion of the code in which the error occurs and I do hope that somebody with more experience in this language can decipher the assumingly little adjustment.

The erro occurs on line "if data (1,4)>10.

data = [];

for k = 1:numfilesperday

filename = files(fileind(k)).name;

data = [data; KAMBs_extractFiles(filename)];

if k == numfilesperday

data(1:4,:) = [];

end

end

if data(1,4)>10

tCol = 4;

elseif data(1,4)<10

tCol = 5;

end

Further I am adding the extraction file coding here, which might be informative too. To this my files are named as: G001_220824v1.... (to v4)

data = dlmread(file);

lastbreak = strfind(file, '/');

lastbreakind = max(lastbreak)+1;

ending = strfind(file, '.');

endingind = max(ending)-1;

filename = file(lastbreakind:endingind);

trials = unique(data(:,2));

maxtri = max(trials);

data = data(end-(maxtri-1):end,:);

end

Thank you for any advice or help.

Seems that with the command

if k == numfilesperday
    data(1:4,:) = []; 
end

you have destroyed the complete matrix "data".

Insert

size(data)

before the if-clause

if data(1,4)>10 
    tCol = 4;
elseif data(1,4)<10
    tCol = 5; 
end

to see the dimension of the array.

Thank you so much for your quick answer and I am sorry for replying so belated. I have added the size (data) part and apparently this is the output:

ans =

0 0

So, basically it considers nothing in the data.

ok, this means you deleted the complete data matrix.
