Non central chi square distribution

[Quantinator]

I know there is a way to get the non central chi square distribution in c language or some other computer software but I am interested in the maths behind it.
I am going through the book handbook of quantitative finance.
The book just has dedicated three/four pages but it is just a huge wall of maths and it doesnt explain any of the steps.
Does anyone have any papers or anyother resources that explain he whole process of computing the distribution and the cev call option formula?
Thanks

The link doesnt work but I have seen the mark schroder paper 1989 paper if that what it was.I need to explain the whole distribution from scratch and build it up I think.
