How to implement the function meijerG

Hi!

How's it going ?

I am solving a scientific article and I find myself with a difficulty.

Does anyone here have the domain of the meijerG function?

I have read the documentation in matlab but the truth is that it is not very clear.

For example in the document it appears like this meijerG(a,b,c,d,z)

What is the input variable corresponding to the one that appears in the figure according to the general definition of this function?
