Matlab程序提示错误：Error using * Inner matrix dimensions must agree.Matlab程序：x=0.01:0.01:9; y=(4.5-x)*sqrt(9*x-x.^2); 提示：Error using * Inner matrix dimensions must agree.
Matlab程序提示错误：Error using * Inner matrix dimensions must agree.
Matlab程序：
x=0.01:0.01:9;
y=(4.5-x)*sqrt(9*x-x.^2);
提示：Error using *
Inner matrix dimensions must agree.
Matlab程序提示错误：Error using * Inner matrix dimensions must agree.Matlab程序：x=0.01:0.01:9; y=(4.5-x)*sqrt(9*x-x.^2); 提示：Error using * Inner matrix dimensions must agree.
程序改成如下：（注：你少加了个点,在（4.5-x）后面加点）
x=0.01:0.01:9;
y=(4.5-x).*sqrt(9*x-x.^2);
plot(x,y)
结果
