Solving Meijer G function!!

I am using MeijerG function. An equation includes negative sign in it, [-1,0,0], but when I use it, I get error.

Can you help me in solving this issue

This is a MuPAD notebook question. You should have mentioned that.

Answer 1

[Walter Roberson]

No pair of parameters ai - bj, i = 1, …, n. j = 1, …, m, should differ by a positive integer.

You violate that. 0 minus -1 is +1, a positive integer.

Answer 2

Walter Roberson's comment of 10 March 2017 is correct. Look up the definition of meijerG. If for any parameter pair a.i, b.j the difference a.i - b.j is a positive integer, the definition involves gamma functions evaluated at non-positive integer values (this is where the gamma function has singularities). meijerG simply is not defined for such parameters.
