2、求助matlab 时域分析程序-峰值、均方根、裕度、峭度x0:0.1:2 * pi；ysin(x)；%信号mamax(y)；%最大最小值(y)；%最小值(y)；%平均pkmami%峰峰值avmean(abs(y))%绝对值的平均值(整流平均值)vavar(y)；%方差标准差(y)；%标准差kukurtosis(y)；%峰度RM rms(y)；% rms Srm/av%波形因数Cpk/RM；%峰值因子krsum (y.4)/sqrt (sum (y.2))%峰度因子Ipk/av%脉冲因子xr mean(sqrt(ABS(y))2；lpk/xr；% margin因子只是我自己用的，所以整理了一下。
