Hi Peter, I finished the fixed rate bond part and a pull request has been raised. Any comment is welcome, Peter:) Regards, Cheng -----邮件原件----- 发件人: Peter Caspers [mailto:pca...@gm...] 发送时间: 2015年2月2日 20:52 收件人: cheng li 抄送: Luigi Ballabio; QuantLib developers 主题: Re: 答复: 答复: 答复: [Quantlib-dev] 答复: Adjoint Greeks Hi Cheng, great, I am looking forward to receive your contributions !
