planetrendering

说明：  带通滤波。该程序用matlab实现梯形窗的带通滤波，可以直接调用(Band-pass filter. Trapezoidal matlab implementation of the program window with a band-pass filter, can be called directly)

说明：  计算有义波高的程序 船舶水动力学方面 是比较专业的程序(Significant wave height calculation procedure for ship hydrodynamic aspects of the program more professional)
