帮忙改个matlab的程序
a=ones(8);
a(1,2)=3;a(1,3)=4;a(1,4)=5;a(1,5)=6;a(1,6)=7;a(1,7)=8;a(1,8)=9;
a(2,3)=3;a(2,4)=4;a(2,5)=5;a(2,6)=6;a(2,7)=7;a(2,8)=8;
a(3,4)=3;a(3,5)=4;a(3,6)=5;a(3,7)=6;a(3,8)=7;
a(4,5)=3;a(4,6)=4;a(4,7)=5;a(4,8)=6;
a(5,6)=3;a(5,7)=4;a(5,8)=5;
a(6,7)=3;a(6,8)=4;
a(7,8)=3;
for j=1:8
c(j)=sum(a(:,j))/40;%求均值
z(j)=var(a(:,j));%求方差
end
for j=1:8
for i=1:40
x(i,j)=(a(i,j)-c(j))/sqrt(z(j));
end
end
f=cov(x);
[v,d]=eig(f);
h=0;g=0;
for m=1:8
g=g+d(m,m);
end
for n=1:8
if d(n,n)>1
h=h+d(n,n);
end
end
k=h/g;
F1=x*v(:,8);
F2=x*v(:,7);
F=d(8,8)/(d(8,8)+d(7,7))*F1+d(7,7)/(d(8,8)+d(7,7))*F2;
[y,q]=sort(F,'descend');
y'
q'

for i=1:40
x(i,j)=(a(i,j)-c(j))/sqrt(z(j));
end
你的i没有40个啊
而且你的z(1,:)=0

帮忙改个matlab的程序帮忙写个简单的matlab程序求matlab大神帮忙改下程序那位能帮忙写个matlab程序能帮忙编个MATLAB程序吗? 求MATLAB高手帮忙改下程序,我的有错误啊,像画三条曲线出来的 matlab程序大神帮忙看看哪里错了怎么改能改出来的还加分! 谢谢! 求大神帮忙写个matlab小球自由落体然后向右弹跳运动的程序, 求大神帮我改下matlab的程序帮忙解释下matlab程序帮忙看下这道MATLAB程序题如何用matlab画这种2个y轴的图?请大家帮忙写个能实现的程序.
