matlab Matrix must be square什么情况?
A为一个1119*2的数组
当我输入A1=inv(A)时
出现matlab Matrix must be square
为什么啊?

matlab Matrix must be square什么情况?A为一个1119*2的数组当我输入A1=inv(A)时出现matlab Matrix must be square 为什么啊?
inv(A)为对矩阵A求逆,必须要求A为方阵,且A要可逆,即A的行列式不为零

matlab的运行问题,Inner matrix dimensions must agree.怎么回事啊? 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. 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 Matrix must be square什么情况?A为一个1119*2的数组当我输入A1=inv(A)时出现matlab Matrix must be square 为什么啊? 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. 超定方程组的Matlab 求法xhat=inv(A'.*A).*A'.*b; Error using ==> times Matrix dimensions must agree.我运行求超定方程组的算法,怎么会出现上述问题?请教高手给出正确的程序. x=0:pi/100:6*pi;b=(cos(x)+i*sin(x))*(x);然后就提示Error using ==> mtimesInner matrix dimensions must agree.了,我是新手,刚接触matlab MATLAB程序,这个程序不知道为什么出现?Error using ==> mpower Matrix must be square. Matlab计算Index exceeds matrix dimensions.为什么?... Matlab中Inner matrix dimensions must agree是怎么回事?h=[200,600,600,600,600];H=[51000 51000 71400 128000 370000];R=6400;a=(h+H+2*R)/2;c=(H-h)/2;b=sqrt(a*a-c*c);t=(0:.1:2)*pi;x=a*cos(t);y=b*sin(t);plot(x,y,'-r')显示第六行Inner matrix dimens matlab程序运行错误 “Z must be a matrix,not a scalar or vector.”syms a b Jm=[1,a,b;2,3,4;6,b,a]MM=det(Jm) [a,b]=meshgrid(-2:0.1:2); surf(a,b,MM);我理解这个错误是说MM是矩阵的意思,这个程序该如何修改才行,而且需要 MATLAB矩阵min已知matrix是一个二维矩阵,请问大虾:matrix=min(matrix,matrix.');是什么含义 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 用MATLAB画出Logistic 模型式子:y=112.5/(1+29*e^(-0.5*x))用plot,他告诉我‘Matrix must be square ’ 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. 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三维图,Matrix dimensions must agree,not rendering mesha=1.5,b=0.5,c=0.2;%高、宽、厚(米);%模型1;s=2*a*b+2*a*c+b*c;%被淋面积;d=1000,vmax=5,w=1e-4/18;%距离(米)、人最大速度(米/秒),降雨量(米/秒)
