hello dolfin developers
I write out a std::vector in XML file format from cpp. Can I read the
XML file in again in python and construct a numpy array?
I know how to do it with a dolfin Vector, but is it possible with a
std::vector<double>? I could not figure out the syntax, i tried
# this is ok
fn = File("data/norm.xml")
div_vec = d.Vector()
a = n.array((11,1))
# fails
fn >> a
# fails
fn >> div_vec.array()
Have you tried:
fn >> div_vec
a = div_vec.array()
yes, that gives the error:
*** Error: Handler stack not empty. Something is wrong!
if i write out a dolfin::Vector in xml, it's all fine with:
fn = File("data/norm.xml")
div_vec = d.Vector()
fn >> div_vec
a = div_vec.array()
but if i write out a std::vector<double> in xml, I can't read it in.
