以下为实验中测量的电压与对应的温度数据.请问在MATLAB里如何等到他们两者之间的关系式!!!!无限感激!
实测电压U1/伏 实测温度/摄氏度
6 30.9
5.5 31.2
5 30.6
4.5 33.2
4 34.8
3.5 36.7

Function: y = p1+p2*x+p3*x^2+p4*x^3+p5*x^4+p6*x^5+p7*x^6+p8*x^7+p9*x^8+p10*x^9

Correlation Coef. (R): 0.999761295022178

不懂
讲解下吧

y=b(1)+b(2)*x+b(3)*exp(b(4)*x+b(5)*x.^2)
b=[47.88309747, -3.475949058, 1.930423563, -1.115223359, .2049872465]
RSS=2.443441710,R2=.998187
可能更好一些.
