Method on @sym: igamma (nu, x)

Symbolic upper incomplete gamma function.

Example:

syms x nu
igamma (nu, x)
  ⇒ (sym) Γ(ν, x)

Note the order of inputs and scaling is different from ‘@sym/gammainc’, specifically:

igamma (nu, x)
  ⇒ (sym) Γ(ν, x)
gammainc (x, nu, 'upper')
  ⇒ (sym)
      Γ(ν, x)
      ───────
        Γ(ν)
