The goal of sciscipy is to give an access to Scilab features inside python.

from scilab import Scilab
sci = Scilab()

x = sci.rand(20, 20)
y = x*x.transpose()
y_inv = sci.inv(y)

The function func in sci.func(x, y) can be a Scilab built-in or any user
defined function so that Scilab libraries can be reused easily in python.
