源码 每次迭代采样不同子区间，error(拟合的均值-实际均值) 先减低后增，改成样本点不变
error 曲线看上去正常,看上去 A 的值离实际很大，不知道是不是和论文的结论一致？
补充:github上代码可能是作者公式写错了
def get_gauss_params(a, b, c):
"""
Calculate gaussian coefficients from parabola coefficients.
See Eqs. (5-7)
"""
mu = -b / (2 * c)
sigma = np.sqrt((-1 / (2 * c)))
#公式写错了
#A = np.exp(((a - b ** 2) / 4 * c))
A = np.exp(a - (b ** 2) / (4 * c))
return A, mu, sigmax更正后的效果
