[求助]matlab gaussian 曲线拟合公式?
我在matlab gaussian 曲线拟合得到的公式:
General model Gauss1:
f(x) = a1*exp(-((x-b1)/c1)^2)
Coefficients (with 95% confidence bounds):
a1 = 0.1224 (0.1188, 0.126)
b1 = 11.4 (11.38, 11.42)
c1 = 0.9094 (0.8781, 0.9407)
怎么与正态分布公式对应不上?
f(x) = ( 1/(k*sqrt(2*3.14159265358979)))*exp(-(x-p)^2/2*k^2)
算出来的两个k不一样,是不是两个公式本来就不一样?
