write double class to .txt file

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?

Answer 1

[ha ha]

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.

save YourFileNameGoesHere.txt ha -ascii -double

[ha ha]

i try your syntax but matlab inform error

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

>> ha = rand(14,3)
ha =
