[Matlab/数学]向量点积问题：向量A,B在dim维的点积.数学上是怎么定义“在某维的点积”啊?有一个语句是dot(A,B,dim),意思是向量A,B在dim维的点积.但是我好像没学过两个向量在某维的点积啊,是怎 matlab的运行问题,Inner matrix dimensions must agree.怎么回事啊? 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? matlab点乘问题Matrix dimensions must agree.function F = DFT(A,B,N,L,fs,chuang)t=(0:N-1)/fsws=2*pi*fsf=A*cos(200*pi*t)+B*cos(240*pi*t);f=f.*chuang;F=fftshift(fft(f,L))w=(-ws/2+(0:L-1)*ws/L)/(2*pi)plot(w,abs(F));ylabel('幅度谱')end 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? Matlab计算Index exceeds matrix dimensions.为什么?... matlab中的点乘怎么表示 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 MATLAB中乘和点乘之间有什么区别? matrix matlab中,Index exceeds matrix dimensions错误问题>> d=find(2380 e=find(X>=2460);>> N11=length(find(X(d+1) 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. 函数点乘在matlab 中怎么表示 matlab问题 matlab问题 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 请教matlab函数plot画点的问题 请教matlab函数plot画点的问题
