=={{header|MATLAB}} / {{header|Octave}}==

The concept of "word size" is not meaningful in Matlab and Octave, uint64 is also available on 32bit-platforms, and there are no pointers. Endianity can be tested with the function below:

<lang MATLAB> function [endian]=endian()

fid=tmpfile();

fwrite(fid,1:8,'uint8');

fseek(fid,0,'bof');

t=fread(fid,8,'int8');

i8=sprintf('%02X',t);

fseek(fid,0,'bof');

t=fread(fid,4,'int16');

i16=sprintf('%04X',t);

fclose(fid);

if strcmp(i8,i16) endian='big';

else endian='little';

end;

</lang>

Output:

<pre> octave:128> computer

x86_64-unknown-linux-gnu

octave:129> endian

endian = little</pre>
