MacRobert's E-Function

$E(p; \alpha_r: \rho_s:x)\equiv {\Gamma(\alpha_{q+1})\over\Gamma(\rho_1-\alpha_1)\Gamma(\rho_2-\alpha_2)\cdots \Gamma(\rho_q-\alpha_q)}$
$\times \prod_{\mu=1}^q \int_0^\infty {\lambda_\mu}^{\rho_\mu-\alpha_\mu-1}(1+\l...
...nfty e^{-\lambda_{q+\nu}}{\lambda_{q+\nu}}^{\alpha_{q+\nu}-1}\,d\lambda_{q+\nu}$
$ \times\int_0^\infty e^{-\lambda_p}{\lambda_p}^{\alpha_p-1}\left[{1+{\lambda_{q...
...p\over (1+\lambda_1)\cdots (1+\lambda_q)x}}\right]^{-\alpha_q+1}\!\!d\lambda_p,$
where $\Gamma(z)$ is the Gamma Function and other details are discussed by Gradshteyn and Ryzhik (1980).
