Code for extracting the special values
显示 更早的评论
Hi all,
I have txt file which contains two columns: the first column is time [hourly resolution], and the second column is the answer of my function (values). I want to extract the values from the second column which are based on daily [I mean 0,1,2,3,...]. and then write it in another txt file, which will have two columns and be like: 0 814 1 745 2 660 3 539 . .
How should I have to write my code? Attached my .txt file here.
I appreciate any help and thanks in advance. Hope to hear from you. Sepideh

% Read original data file:
M = dlmread('remaining particles total.txt','\t');
H = min(M(:,1)):max(M(:,1));
[X,Y] = ismember(H,M(:,1));
assert(all(X),'Some hour values are missing')
% Write new data file:
fid = fopen('newfile.txt','wt');
fprintf(fid,'%d\t%d\n',M(Y,:).');
fclose(fid);
This creates the following new text file:
0 814
1 745
2 660
3 539
4 420
5 355
6 303
