MATLAB: How to read 16-bit text with Matlab

16-bitbenchlinkdetect utf encodingMATLABtext;unicode

I have an Agilent 34970A data logger with their BenchLink software. This puts out a .csv file that Excel reads with no trouble. But Matlab cannot import it because it's 16 bit text. The first two bytes are 0xFF 0xFE, then after that every text byte is followed by a NULL (0x00). I wrote a function to read it, but I was hoping for the ability to read it directly, without having to programmatically skip the NULLs.

MATLAB does not handle UTF-16LE files. You might wish to use the source code I posted in http://uk.mathworks.com/matlabcentral/answers/267176-read-and-seperate-csv-data#answer_209938 which reads csv files from any of the UTF-8 / UTF-16 / UTF-32 encodings

Your test code forgot to mention fid in the fprintf() so it did not output anything.

Remember that when you use fprintf() with the syntax fprintf(fid, A_String) that the values in A_String are treated as being the format specifier and so are subject to interpretation. The exception to this is if you are sending to a serial device or instrument, in which ase fprintf(fid, A_String) is equivalent to fprintf(fid, '%s\n', A_String) . If you want the exact string sent, you should use fwrite(fid, A_String) instead of fprintf(fid, A_String)

Anyhow, what you might be running into is that fopen() with so few parameters opens the file with the default character encoding for your system. You should fopen() with 4 parameters:

fid=fopen('test','w', 'n', 'ISO-8859-1')

See http://www.mathworks.com/help/matlab/ref/fopen.html#inputarg_encodingIn

(Note: the third parameter, 'n' in this example, cannot be skipped or left at '' or [] if you need to provide the encoding.)

MATLAB: I am trying to extract data from a .csv file that contains a header but I keep getting an empty array in return.

Try this:

[D,S] = xlsread('TCData_1.csv');
DataCell = cellfun(@(x)str2double(regexp(x, ',', 'split')), S(9:end), 'Uni',0);
DataMtx = cell2mat(DataCell);
