Find maxima of a function
I have a Gaussian mixture model with some parameters
mean=(506.8644,672.8448,829.902)
sigma=(61.02859,9.149168,74.84682)
c=(0.1241933, 0.6329082, 0.2428986)
And the plot look something like below.[image: enter image description here]

Also, if I change my parameters to
mean=(2.15,2.0,2.9)
sigma=(0.1,0.1,0.1)
c=(1/3,1/3,1/3)
Then plot would change to[image: enter image description here]

Is there any way to find the maxima. I have tried Newton's method but it
gave me th...
