Matrix dimensions must agree该怎么办?如题.急

Matlab计算Index exceeds matrix dimensions.为什么?... Matrix dimensions must agree该怎么办?如题.急 matlab的运行问题,Inner matrix dimensions must agree.怎么回事啊? matrix 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. x=0:100 y=1/(1+exp(x)) plot(x,y)出现错误 Matrix dimensions must agree. MATLAB :(Inner)Matrix dimensions must agree.我输入fh=fl.*fz,它显示timesMatrix dimensions must agree.我输入fh=fl*fz,它又显示mtimesInner matrix dimensions must agree.为什么不管用不用点乘都是Error using呢? 请问如何在matlab中画函数图形 r=cosh(t)*exp(-t/100) 为什么会出现 Inner matrix dimensions must agree.如何画 程序代码 sym_digits=sym('[1 2 3;a b c;sin(x)cos(y)tan(z)]') 出现错误?Index exceeds matrix dimensions matlab中数字后加一个点有什么用?比如plot(x,sin(1./x));为什么改成1.0就出错?Error using / Matrix dimensions must agree. matlab中,Index exceeds matrix dimensions错误问题>> d=find(2380 e=find(X>=2460);>> N11=length(find(X(d+1) 在matlab中输入想画曲线图>> x=-2*pi:0.1:2*pi;>> y=x*tan(x);Error using ==> mtimesInner matrix dimensions must agree. matlab编程问题?Error using ==> mtimes Inner matrix dimensions must agree.t=0:0.01:10;x=2*t; y=1-exp(-0.5*t)*cos(x); Error using ==> mtimesInner matrix dimensions must agree.只要cos里面是2*t就会有这问题,如果仅仅是2就没问题.为 matlab中 Error using ==> mtimes Inner matrix dimensions must agree.程序A=[3 8 5 1 2];B=[3 4 5 2 6];>> i=1:length(A);>> i=1:length(B);>> sum=sum(A(i)+A(i)*B(i))Error using ==> mtimesInner matrix dimensions must agree. 求助...555急急..万分感谢.英文数学题if matrix A has dimensions m*n and matrix B has dimensions n*p,where m,n,and p are distinct positive integers,which of the following statements must be true?1,the product BA does not exist2,the product matlab Error using ==> mtimes Inner matrix dimensions must agree.x=0:pi/50:4*pi;y1=exp(x/3)*sin(3*x);y2=exp(x/3);y3=-exp(x/3);plot(x,y1,'b*',x,y2,'r.',x,y3,'r.'),grid onError using ==> mtimesInner matrix dimensions must agree. matlab错误：Warning:Matrix dimensions must agree,not rendering mesh.>> load V1.txt>> v1=V1(:,1);>> i1=V1(:,2);>> v2=V1(:,1);>> surf(v1,i1,v2);Warning:Matrix dimensions must agree,not rendering mesh.请问这是怎么回事?V1.txt的内容如下： Matlab出现Inner matrix dimensions must agree问题x=linspace(0,2*pi,30);y=sin(x)*cos(x);plot(x,y)点回车就出现：? Error using ==> mtimesInner matrix dimensions must agree.这是怎么回事?怎么解决?
