示例1: test_polyvander3d
# 需要导入模块: from numpy.polynomial import polynomial [as 别名]
# 或者: from numpy.polynomial.polynomial import polyvander3d [as 别名]
def test_polyvander3d(self):
# also tests polyval3d for non-square coefficient array
x1, x2, x3 = self.x
c = np.random.random((2, 3, 4))
van = poly.polyvander3d(x1, x2, x3, [1, 2, 3])
tgt = poly.polyval3d(x1, x2, x3, c)
res = np.dot(van, c.flat)
assert_almost_equal(res, tgt)
# check shape
van = poly.polyvander3d([x1], [x2], [x3], [1, 2, 3])
assert_(van.shape == (1, 5, 24)) 示例2: test_polyvander3d
