你好,这么做,现将这一部分
function [w]=w01(t)
c0=-6.0436117*10^3;c1=1.89318833*10;c2=-2.8238594*10^(-2);
c3=1.7241129*10^(-5); c4=2.858487;
E=exp(c0*(t+273.16)^(-1)+c1+c2*(t+273.16)+c3*(t+273.16)^(2)+c4*log(t+273.16));
Pa=1.013*10^5;
w=0.662*E/(Pa-E);
end
保存 命名为 w01.m 文件,放到桌面上,再将余下的部分改写为：
syms t2;
ma=0.03;
cw=4.2*10^3;
w1=w01(30)
w2=w01(t2)
L=29400;
h=0.00585*(t2+273.16)^3-0.497*(t2+273.16)^2+19.87*(t2+273.16)-207.61;
L=((ma+ma*(w2-w1))*h+(0.1-ma*(w2-w1))*t2*cw-1.5255e+003);
A=solve(L,t2)
运行就好!
