MATLAB输入f=exp((-x)^2)为什么显示?Error using ==> mpower Matrix must be square.
包括输入y=(exp(x^3)-1)/(1-cos(sqrt(x-sin(x))))也出现?Error using ==> mpower
Matrix must be square.
包括输入y=(exp(x^3)-1)/(1-cos(sqrt(x-sin(x))))也出现?Error using ==> mpower
Matrix must be square.

y=(exp(x.^3)-1)./(1-cos(sqrt(x-sin(x))))
加2个点就可以了.这个是点对点运算.(.^和./)
再问: >> z=((x^2)/9)-((y^2)/4); >> plot3(z) 有问题吗?我想画一个马鞍形。
再答: x = -10:0.1:10; y = -10:0.1:10; [X,Y] = meshgrid(x,y); z=((X.^2)/9)-((Y.^2)/4); surf(X,Y,z) shading flat; ---------------------------- 哇塞,好漂漂啊
