matlab总是mpower Matrix must be square.b=0:0.01:5;x=b;f(x)=1/(((1-x.^2)^2+(2*0.5*x)^2)^0.5);plot(x,f(x))

matlab ? Error using ==> mpower Matri>> x=linspace(-2,2,100);>> y=(x^2)*sin(x^2-x-2);plot(x,y)? Error using ==> mpowerMatrix must be square.这个要怎么改? matlab总是mpower Matrix must be square.b=0:0.01:5;x=b;f(x)=1/(((1-x.^2)^2+(2*0.5*x)^2)^0.5);plot(x,f(x)) matlab程序运行总是出现? Error using ==> sym.mpower Matrix must be square. 加了“.”还是不行呀m=zeros(1,50);a=zeros(1,50);b=zeros(1,50);f0=zeros(1,50); syms d x1 x2 e; m(1)=1;c= MATLAB程序,这个程序不知道为什么出现?Error using ==> mpower Matrix must be square. Matlab平方怎么输入t=(-10*pi:0.001:10*pi);y= mpower(sin(5*t),2);plot(t,y,'-b')grid onaxis tight为什么提示错误?
