示例1: test_fspace_vector_real_imag
# 需要導入模塊: from odl import FunctionSpace [as 別名]
# 或者: from odl.FunctionSpace import zero [as 別名]
def test_fspace_vector_real_imag():

f = cspace.element(cfunc_2d_vec_oop)
# real / imag on complex functions

assert all_equal(out_mg, cfunc_2d_vec_oop(mg).imag)
# real / imag on real functions, should be the function itself / zero
