想用matlab画出下列程序中Y随T变化的点图
T=1200:10:1400a=exp(-(2.98*log(T)+4*T/100000+12500/T/T+47787/T-52.01)/1.987);b=exp(-(...
T=1200:10:1400
a=exp(-(2.98*log(T)+4*T/100000+12500/T/T+47787/T-52.01)/1.987);
b=exp(-(5.79*log(T)+1.75*T/10000+48150/T/T+92542/T-116.93)/1.987);
c=exp(-(-0.42*log(T)+1.1*T/10000-89000/T/T+114925/T-76.16)/1.987);
p=[1 0 -b -2*(a*b-c^2)];
A=roots(p);
Y=A(1); 展开
