MATLAB Central Newsreader - textread with endoflines

textread with endoflines

Dear Matlaber

I have sensor data reading as follows:

-SENSOR/DESCRIPTION
*-------------------------
GOLD 08:01:00 108.5
GOLD 08:01:06 086.6
GOLD 08:01:12 085.0
GOLD 08:01:18 080.3
-/ Finish
+ (c) thank you

I use the following syntax to read the data (in txt file):
[sensor,hour,min,sec,param]=textread('sensor.txt','%4s %2d:%2d:%2d %f','delimiter',',','headerlines',2,'endofline','\n');

Output: ??? Trouble reading literal string from file (row 1, field 5) ==> 1:00 108.5\n

Do you have another way? Your time to response this small problem is appreciated.

Can I suggest you use textscan instead?
fid =3D fopen('sensor.txt', 'r')
C =3Dtextscan(fid, '%s %d:%d:%d %f\n', 'headerlines', 2)
fclose(fid)

C is a cell array of vectors containing the various things ... e.g.
C{1} would be sensor, C{2} hour, C{3} minute, etc.

Hope that helps,

Richard
