I'm looking for a function to calculate the value of a polynomial with multiple variables. For 2d polynomials, I use numpy.polyval, I have values of coefficients as a list and value for x.
I wonder if there is a similar function for x, y, z space so that my input was values of coefficients and value for x, y.

Evaluate a 2-D polynomial at points (x, y).
This function returns the value
p(x,y) = sum_i,j c_i,j * x^i * y^j
The parameters x and y are converted to arrays only if they are tuples
or a lists, otherwise they are treated as a scalars and they must have
the same shape after conversion. In either case, either x and y or
their elements must support multiplication and addition both with
themselves and with the elements of c.
If c has fewer than two dimensions, ones are implicitly appended to
its shape to make it 2-D. The shape of the result will be c.shape[2:]
+ x.shape.
Parameters:
x, y : array_like, compatible objects
The two dimensional series is evaluated at the points (x, y), where x
and y must have the same shape. If x or y is a list or tuple, it is
first converted to an ndarray, otherwise it is left unchanged and, if
it isn’t an ndarray, it is treated as a scalar.
c : array_like
Array of coefficients ordered so that the coefficient of the term of
multi-degree i,j is contained in c[i,j]. If c has dimension greater
than two the remaining indices enumerate multiple sets of
coefficients.
Returns:
values : ndarray, compatible object The values of the two dimensional
polynomial at points formed with pairs of corresponding values from x
and y.

Evaluate a 2-D polynomial at points (x, y).
This function returns the value
p(x,y) = sum_i,j c_i,j * x^i * y^j
The parameters x and y are converted to arrays only if they are tuples
or a lists, otherwise they are treated as a scalars and they must have
the same shape after conversion. In either case, either x and y or
their elements must support multiplication and addition both with
themselves and with the elements of c.
If c has fewer than two dimensions, ones are implicitly appended to
its shape to make it 2-D. The shape of the result will be c.shape[2:]
+ x.shape.
Parameters:
x, y : array_like, compatible objects
The two dimensional series is evaluated at the points (x, y), where x
and y must have the same shape. If x or y is a list or tuple, it is
first converted to an ndarray, otherwise it is left unchanged and, if
it isn’t an ndarray, it is treated as a scalar.
c : array_like
Array of coefficients ordered so that the coefficient of the term of
multi-degree i,j is contained in c[i,j]. If c has dimension greater
than two the remaining indices enumerate multiple sets of
coefficients.
Returns:
values : ndarray, compatible object The values of the two dimensional
polynomial at points formed with pairs of corresponding values from x
and y.
