Data extraction from a text file.
显示 更早的评论
I have the following data:
74
: 69
: 65
: 50
: 39
: 28
: 19
: 8
I created the following code to read the data:
fid=fopen('kirby1.txt');
data=textscan(fid,'%f','delimiter',':');
but it turns the ":" into "NAN". Is there a way to read the data without the ":"?
Desire output:
74
69
65
50
39
28
19
8
Thanks for your help.

Does the first line differ from the others?
I guess the NaNs are the non-excisting values before ":".

If all lines have the same format try
data=textscan(fid,':%f');
--- Cont. ---
This work with R2012a
fid = fopen( 'cssm.txt' );
cac = textscan( fid, ':%f' )
where cssm.txt contains
: 74
: 69
: 65
...
--- Cont. ---
Or if the first line differs
function cssm()
fid = fopen( 'cssm.txt' );
ca1 = textscan( fid, '%f', 1 )
ca2 = textscan( fid, ':%f' )
end
where cssm.txt contains
74
: 69
: 65
...

It is difficult for me to guess the reason to the error you see!
You didn't answer my question in my comment on your question.

Kirby, please show your line of code for the textscan()

f = fopen('yourtextfile.txt');
c = textscan(f,'%s');
fclose(f);
out = str2double(c{:}(1:2:end));
