Ok I seem to have got the most of the problem solved, I just need an expert eye to pick my error as I am stuck.
I have a file of length [125 X 27] and I want to convert it to a file of length [144 x 27]. Now, I want to replace the missing files (time stamps) rows of zeros. (ideally its a 10 min daily average thus should have file length of 144)
Here is the code I am using:
fid = fopen('test.csv', 'rt');
data = textscan(fid, ['%s' repmat('%f',1,27)], 'HeaderLines', 1, 'Delimiter', ',');
fclose(fid);
%//Make time a datenum of the first column
time = datenum(data{1} , 'mm/dd/yyyy HH:MM')
%//Find the difference in minutes from each row
timeDiff = round(diff(datenum(time)*(24*60)))
%//the rest of the data
data = cell2mat(data(2:28));
newdata=zeros(144,27);
for n=1:length(timeDiff)
if timeDiff(n)==10
newdata(n,:)=data(n,:);
newdata(n+1,:)=data(n+1,:);
else
p=timeDiff(n)/10
n=n+p;
end
end
Can somebody please help me to find the error inside my for loop. My output file seems to miss few timestamped values.

Can somebody help me to figure out the uiget to read the above file??
i am replacing
fid = fopen('test.csv', 'rt');
data = textscan(fid, ['%s' repmat('%f',1,27)], 'HeaderLines', 1, 'Delimiter', ',');
fclose(fid);
With
[c,pathc]=uigetfile({'*.txt'},'Select the file','C:\data');
file=[pathc c];
file= textscan(c, ['%s' repmat('%f',1,27)], 'HeaderLines', 1, 'Delimiter', ',');
And its not working
%
NEW ADDITION to old question
p = 1; %index into destination
for n = 1:length(timeDiff)
% if timeDiff(n) == 10
% newfile(p,:) = file(n,:);
% newfile(p+1,:)=file(n+1,:);
% p = p + 1;
% else
% p = p + (timeDiff(n)/10);
% end
q=cumsum(timeDiff(n)/10);
if q==1
newfile(p,:)=file(n,:);
p=p+1;
else
p = p + (timeDiff(n)/10);
end
end
xlswrite('testnewws11.xls',newfile);
even with the cumsum command this code fails when my file has 1,2 time stamps in middle of long missing ones
example
8/16/2009 0:00 5.34
8/16/2009 0:10 3.23
8/16/2009 0:20 2.23
8/16/2009 0:30 1.23
8/16/2009 0:50 70
8/16/2009 2:00 5.23
8/16/2009 2:20 544
8/16/2009 2:30 42.23
8/16/2009 3:00 71.23
8/16/2009 3:10 3.23
My output looks like
5.34
3.23
2.23
