Can anyone help with this tutorial question?

Consider the following non-linear system of equations:
g(x; y; z) = xyz – x^2 + y^2 - 1.34 = 0 ;
h(x; y; z) = xy – z^2 - 0.09 = 0 ;
i(x; y; z) = e^x – e^y + z – 0.41 = 0 :
Write a Scilab function that will evaluate g, h and i at any point (x; y; z). Your function should return these function values as a single vector and use as its input a single vector containing the values of x, y and z.

Any help would be appreciated.
