Equation for imgaussfilt?

Hi,

I have been using the Matlab built-in function imgaussfilt for some time now and I need to report the specific Gaussian used to filter my images in a paper I'm writing.

I'm sure the equation used to be written on the ref page for imgaussfilt but now I can't find it.

Looking inside the function I can see that the Gaussian appears to be made by images.internal.createGaussianKernel but this is an internal function (so no .m file I can read).

Does anyone have any idea where I can get the full equation?

Thanks,

M.

That file is a plain m-file and can be read.
