作业帮用matlab求曲线斜率大于某值的区域,如何求以下曲线斜率大于某值的区域?最好能给程序出来 x1=1:0.1:10;x2=1:0.1:10;x3=1:0.1:10;y1=100./sqrt(x1);y2=150./sqrt(x2);y3=200./sqrt(x3);x=[x1;x2;x3]';y=[y1;y2;y3]';plot(x,y)

如何求以下曲线斜率大于某值的区域?
最好能给程序出来
x1=1:0.1:10;
x2=1:0.1:10;
x3=1:0.1:10;
y1=100./sqrt(x1);
y2=150./sqrt(x2);
y3=200./sqrt(x3);
x=[x1;x2;x3]';
y=[y1;y2;y3]';
plot(x,y)
