示例1: test_chebvander2d
# 需要导入模块: from numpy.polynomial import chebyshev [as 别名]
# 或者: from numpy.polynomial.chebyshev import chebvander2d [as 别名]
def test_chebvander2d(self):
# also tests chebval2d for non-square coefficient array
x1, x2, x3 = self.x
c = np.random.random((2, 3))
van = cheb.chebvander2d(x1, x2, [1, 2])
tgt = cheb.chebval2d(x1, x2, c)
res = np.dot(van, c.flat)
assert_almost_equal(res, tgt)
# check shape
