快速傅里叶变换

说明：  lda是一个集合概率模型，主要用于处理离散的数据集合，目前主要用在数据挖掘（dm）中的text mining和自然语言处理中，主要是用来降低维度的(lda is a set of probability models, mainly for dealing with discrete data sets, the key used in data mining (dm) in the text mining and natural language processing, is mainly used to reduce dimension)

在matlab中，通过space carving实现三维重构(n the matlab, through space carving realize 3 d reconstruction)
