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 the wrong output.
Like in general some common solution, which would work on all the cases, is
needed.Can someone suggest me how can I achieve this
Thanks in advance
