Let' say , I have the data in Matlab with the result is ha=14x3 double.
ha=[ 6.74483465234e+05 1.512013286060e+06 -11.6250
6.74483565235e+05 1.512013586059e+06 -11.1250
6.74483665235e+05 1.512013186059e+06 -11.6150
............................................................]
How can I convert "ha" to the file with extension file name .txt?

dlmwrite('output.txt', ha, 'delimiter','\t','newline','pc','precision',13);
where "precision": using a precision of 13 significant digits. https://www.youtube.com/watch?v=PGPBCAPd9Vg&feature=youtu.be

Two steps are not needed. If you already have ha then just the dlmwrite() would be needed.

Which MATLAB release are you using? And is it possible there was a special character in the file name?
