中文说明：
Compressive Sampling是最近讨论非常热烈的数据处理方法。用一个与变换基不相关的观测矩阵将变换所得到的高维信号投影到一个低维空间上，然后通过优化求解从这些少量的投影中以高概率重构出原信号。
English Description：
Compressive sampling is a very popular data processing method recently. A small number of high-dimensional signals are transformed from the high-dimensional projection to a low-dimensional signal.
