I have this text file and I want to store the fist 4 columns, starting from the third row in a variable called 'Time'
The text file is this,
http://www.ndbc.noaa.gov/data/realtime2/41053.txt
I am proceding the following way,
clc,clear all
fid = urlwrite('http://www.ndbc.noaa.gov/data/realtime2/41053.txt','SJ.txt'); % URL from CARICOOS
Data = SJ;
Time = Data{1,1};
The following is the function code,
function Data = SJ
fid = fopen( 'SJ.txt' );
Data = textscan( fid, '%d%d%d%d%d%f%f%f%f%f%s%s%s%f%f' ...
, 'Delimiter' , ' ' ...
, 'CollectOutput' , true ...
, 'HeaderLines' , 2 ...
, 'MultipleDelimsAsOne' , true ...
, 'Whitespace' , '' ...
);
fclose( fid );
end
I keep getting this error,
Error in ==> SJ at 3
end
??? Output argument "Data" (and maybe others) not assigned during call to
"C:\Users\User\Documents\MATLAB\CARICOOS\SJ.m>SJ".
Error in ==> SJ_F at 4
Data = SJ;

To check: is your variable name assigned to by the textscan() exactly the same as the variable name on the left side of the "=" in your "function" line? It looks like it is in what you posted, but please confirm in your original source.
You will probably have to put a breakpoint in at the textscan line, and check the value of "fid" and step once to have the textscan() executed, then check the workspace to confirm that it was assigned.
