A typo

[zhengow]

Dear Pili,

Hi, I am one of your readers, thanks for your paper.
Actually, I think there is a typo in Page12, Eample 6, formula (63), I think the transpose should be outside. Details is attached, please take a look.

Sincerely,
Cheng

Thanks Cheng! I think the transpose should be outside. It had been a long time and I don't have working Tex env at hand. Let's leave this issue here until someone can help re compile the file. Thanks again.
