Hi all,
how do I evaluate a bivariate polynomial
p(x,y)=c_0 + c_1 x + c_2 y +c_3 x**2 + c_4 x*y+ c_5 y**2 +
c_6 x**3 + c_7 x**2*y + c_8 x*y**2+c_9*y**3 + \dots
in numpy ?
In case of univariate polynomials I can use np.polyval.
Any pointer would be appreciated.

Hi all,
The dot product can be defined for two vectors x and y by
x·y=|x||y| \cos(\theta),
where theta is the angle between the vectors and |x| is
the norm.
Now assume that we have arrays(matrices)
X = [x_1, ..., x_m]
Y = [y_1, ..., y_s]
