classification

This letter addresses the problem of fetal electrocardiogram (FECG) extraction. A class of source extraction algorithms is proposed, which uses a combination of two di® erent approaches: Barros s source extraction approach and HyvÄ arinen s ˉxed- point approach.

rgb2lab：rgb颜色空间向lab颜色空间转换的matlab代码，对此变换要使用不求甚解的童鞋们可以直接调用~(rgb2lab：colorspace of rgb translate to colorspace of lab。Just for the beginner~)

基于三电平滞环有源电力滤波器（APF）的仿真设计，包括（谐波检测， 电流跟踪环节） Z域(Based on three-level hysteresis active power filter (APF) simulation design, including (harmonic detection, current tracking links) Z domain)

本程序是对轴承应力、应变进行必要的计算，从而获取较为准确的计算结果。(This procedure is necessary to calculate the bearing stress and strain, so as to get more accurate calculation results.)
