MATLAB画多个曲线的平均值曲线
多个二维曲线:x代表时间,y代表值
比如曲线1：x_1=[1,2,3,4,5],y_1=[1,2,3,4,5],曲线2：x_2=[2,3,4,5,6,7,8],y_2=[2,3,4,5,6,7,8],怎样画这两个曲线的平均值曲线,当然,时间x不能平均,只对同一x点下的y值进行平均
MATLAB画多个曲线的平均值曲线多个二维曲线:x代表时间,y代表值比如曲线1：x_1=[1,2,3,4,5],y_1=[1,2,3,4,5],曲线2：x_2=[2,3,4,5,6,7,8],y_2=[2,3,4,5,6,7,8],怎样画这两个曲线的平均值曲线,当然,时间x不能平均,
x1 = [1 2 3 4 5];
x2 = [2 4 5 6];
y1 = [4 6 8 9 2];
y2 = [3 6 2 5];
x =unique([x1 x2]); %时间点合并,去掉重复的值,并排序
y=[];
for i=x
index1 = x1 == i;
index2 = x2 == i;
if sum(index1)>0 && sum(index2)>0 %若某时间点上有两个值,取平均
y(i)=mean([y1(index1) y2(index2)]);
elseif sum(index1)>0 %单个值,则不变
y(i)=y1(index1);
elseif sum(index2)>0
y(i)=y2(index2);
end
