Re: [Q:] How to use "xlswrite()" in Octave on Mac OS X Mavericks?

[TAISO, Renpoo]

Thanks Philip,

But it causes the error message like below. (after following your 
instruction)

The code for xlswrite() is like this.
> xlswrite( outputDataFileName, res, 'Sheet1', 'A1:XFD1048576', 'oct' ); 

Is it necessary to install another package?

Thanks in advance,
