How to read a text file and create a structure array?
显示 更早的评论
Hey,
I have a large data set which is divided into 3 columns and and in two separate text files. I would like to read the data from text files, add the data together so that it is in continuous columns and create a structure from it.
The text files' data is like:
$ABC, 00025, 39.24
. , . , .
. , . , .
I tried this code:
fid = fopen('mydata.txt');
C = textscan(fid, '%s%d8%f32');
fclose(fid);
f = {'Title','Time','Dist'};
s = cell2struct(C,f,2);
but it returns a blank structure array. Can somebody please tell me what is wrong with the code?
Thanks.

Try to skip the second comma.
C = textscan(fid, '%s%d8%*s%f32');

A simple possibility is to load the 2nd file in a 2nd cell and combine them in a for loop.
...
fid = fopen('mydata2.txt');
C2 = textscan(fid,'%s %d8 %f32','delimiter',',');
fclose(fid);
for i = 1:numel(C1)
C{i} = [C1{i}; C2{i}];
end
...
