If you are willing to consider a library, pandas (http://pandas.pydata.org/) is a library built on top of numpy which amongst many other things provides:

智能数据对齐和丢失数据的集成处理:在计算中获得基于标签的自动对齐，并轻松将混乱的数据处理为有序的形式

Intelligent data alignment and integrated handling of missing data: gain automatic label-based alignment in computations and easily manipulate messy data into an orderly form

在金融行业中，我已经使用了将近一年的时间，在该行业中，丢失和对齐不当的数据已成为常态，这确实使我的生活更轻松.
