matlab plot长度出错 程序在这里syms a b;c=[a b]';A=[13.0756,

网友回答

syms a b;
c=[a b]';
A=[13.0756,13.1448,13.2129,13.2802,13.3474,13.7054,13.7440,13.7828,13.8216,13.8606];
B=cumsum(A);
n=length(A);
for i=1:(n-1)
C(i)=(B(i)+B(i+1))/2;
endD=A;D(1)=[];
D=D';E=[-C;ones(1,n-1)];
c=inv(E*E')*E*D;
c=c';a=c(1);b=c(2);
F=[];F(1)=A(1);
for i=2:(n+10)
F(i)=(A(1)-b/a)/exp(a*(i-1))+b/a;
endG=[];G(1)=A(1);
for i=2:(n+2)
G(i-1)=F(i)-F(i-1);
endt1=2005:2014;
t2=2015:2025;
G;a;b;
plot(t1,A,'o')
hold on
plot(t2,G')
hold off按上面语句试试
