textscan not working with double quotation marks

조회 수: 2(최근 30일)
I am using textscan to read a .txt file into matlab but i am having some troubles. The data looks like (first two lines)
1950 "Afghanistan" 8150.368 n/a n/a n/a n/a n/a
1951 "Afghanistan" 8284.473 n/a n/a n/a n/a n/a
and i am using textscan as
PWT = 'Data ind\PWT6.txt';
fid =fopen(PWT);
tmp = textscan(fid,'%f %q %f %f %f %f %f %f','delimiter','\r');
The first column is read ok, the countries are all stored on tmp{1}, but it seems like all the rest is stored in tmp{2} when i actually only want the countries there. Am i using %q wrong or what is going on ?
Thanks :)

"delimiter" is the character used to recognize the end of strings, so when you use \r you are asking the string to go to the end of the line.
What you should do is fopen(PWT, 'rt') for text mode, and not set a delimiter.

I added the treatasempty option and i also realized that i had stupidly taken the wrong format, there are 10 variables not 8 ! this gave me quite a headache :)
Thanks for all the help Walter, it was immensely helpful.
Thanks :)
