Gaussian fit to hist3()

Hello, I am trying to obtain the mu and sigma parameters from a 3D histogram colormap.

My code is the following:

biny = ceil(Par.cryst_lung_y/Par.pixel_image);
binx = ceil(Par.cryst_lung_x/Par.pixel_image);
% biny and binx are two integers
y_image  = [output.y_rec 0 Par.cryst_lung_y];
x_image  = [output.x_rec 0 Par.cryst_lung_x];
%vectors representing the x and y positions
[Counts,Centers]=hist3([y_image' x_image'],[biny binx]);

I would like to know if it is possible to obtain the sigma parameter in particular, considering the counts and centers. Any tips would be greatly appreciated, thank you in advance.
