,求y的最大值、最小值、均值和标准差
正确答案:
>> x=0:0.02*pi:2*pi;
>> y=sin(x);
>> ymax=max(y)
>> ymin=min(y)
>> ymean=mean(y)
>> ystd=std(y)
ymax =
1
ymin =
-1
ymean =
2.2995e-017
ystd =
0.7071
>> y=sin(x);
>> ymax=max(y)
>> ymin=min(y)
>> ymean=mean(y)
>> ystd=std(y)
ymax =
1
ymin =
-1
ymean =
2.2995e-017
ystd =
0.7071
