求教怎么用matlab求解logistic参数?
数据是这些:
t=[0,1,2,3,4,5,6,7,8,9]
y=[37,45,72.4,85.5,115,146,191,216,246,289]
方程是y=(1-(1-(k/37)*exp(-r*t)))
这里面的参数是k和r
y=k/(1-(1-(k/30)^b)*exp(-r*b*(c0*t^2+c1*x)))^(1/b)
这里的参数是k,r,b,c0,c1
但是我把他的数据和方程改了之后放在matlab7.11里面运行报错,

两种方法:1,通过数据运算,简化logistic模型为线型,而后用矩阵相除求解.2,拟合法,用 nonlinfit命令.
