matlab 出现Subscript indices must either be real positive integers or logicals样的错误这是2007年B题的程序：st=3748;en=2160;y=1;za=[];for i=1:k(st)for j=1:k(en)if Z(en,j)==Z(st,i)df=round(Z(en,j));aa=find(L{df,4}==st);%AAbb= find(L{df,4}

matlab为什么出现 Subscript indices must either be real positive integers or logicals.为什么出现>> A=[2 -3 -2;-1 2 1;4 -7 -6];>> C=det(A)Subscript indices must either be real positive integers or logicals. 用matlab图像配准中出现Subscript indices must either be real positive integers or logicals是什么题I=imread('lily.jpg');lily=rgb2gray(I);M=imread('flowers.jpg');flowers=rgb2gray(M);%选择图像的配准区域imshow(lily)figure,imshow(flowe lingo中出现问题：subscript out of range on attribute, matlab 出现Subscript indices must either be real positive integers or logicals样的错误这是2007年B题的程序：st=3748;en=2160;y=1;za=[];for i=1:k(st)for j=1:k(en)if Z(en,j)==Z(st,i)df=round(Z(en,j));aa=find(L{df,4}==st);%AAbb= find(L{df,4} matlab中for语句画图,Subscript indices must either be real positive integers or logicals.for ii=0.1:1x=0:100y(ii)=(L-ii*hg)/(ii*hg)*x-G*b/hg;plot(x,y(ii))hold onend出现Subscript indices must either be real positive integers or logicals.这个 matlab运行 >> x=1:0.01:200; >> a=max(x);出现Subscript indices must either be real positive integers orlogicals.程序明显没有问题,在2012b上可以运行,系统版本2010b lingo中出现问题：subscript out of range on attribute,请尽量说的详细点 matlab仿真老是出现错误,请问怎么改?clear;clc;deta=2;w=2.5;theta=0;a=linspace(-10,10,25);b=linspace(-1.0,1.0,25);[x,y]=meshgrid(a,b);s(x,y)=exp(-0.5*((x/deta)^2+(y/deta)^2)).*sin(w*(x*cos(theta)+y*sin(theta)));plot3(x,y,s(x,y)); Subscript matlab 运行下面的程序出现一些错误,请帮忙看看错误在哪里,谢谢.程序syms x n mn=0;m=1377*10^6;x=0.1:0.01:6;f(x)=(x.*19.1*300*300*pi.*(1-(sin(2*pi.*x))/(2*pi.*x))-n)/((3*x-1.25)*360);plot(x,f(x))运行出错?
