Command save writes to a nonreadable text file
显示 更早的评论
When I execute the below Script file
x = 2; y = x^5;
save result.txt y
and open result.txt in MATLAB, the text shown is not readable. 
What tpye of encoding is this? I know that when I add -ascii the text becomes readable, but I'm curious to learn the type of encoding above and why is it the default text file.

The save command as written is creating a mat file. To create a text file, use the '-ascii' flag.
x = 2;
y = x^5
save result.txt y -ascii

To expand slightly:
save() does not examine the file extension to figure out whether binary or text form is desired. save() always writes in binary unless you specifically ask for text.
