legval2d
(x, y, c)[source]¶ Evaluate a 2D Legendre series at points (x, y).
This function returns the values:
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 is a 1D array a one is implicitly appended to its shape to make it 2D. The shape of the result will be c.shape[2:] + x.shape.
 Parameters
 x, yarray_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.
 carray_like
Array of coefficients ordered so that the coefficient of the term of multidegree i,j is contained in
c[i,j]
. If c has dimension greater than two the remaining indices enumerate multiple sets of coefficients.
 Returns
 valuesndarray, compatible object
The values of the two dimensional Legendre series at points formed from pairs of corresponding values from x and y.
