description:
Implemented x.array() and A.array() for GenericVector and GenericMatrix in PyDOLFIN,
both returning a numpy array with a copy of the data. (NB! dense matrix!).
Try f.ex.:
In [7]: A = assemble(u*v*dx, mesh)
In [8]: B = A.array()
In [12]: import scipy.linalg
In [13]: scipy.linalg.eigvals(B)
Out[13]:
array([ 0.08803702+0.j, 0.05652695+0.j, 0.05015566+0.j, 0.06728417+0.j,
0.01369043+0.j, 0.01388889+0.j, 0.00755545+0.j, 0.02386164+0.j,
0.02406092+0.j, 0.02966277+0.j, 0.01663435+0.j, 0.00759757+0.j,
0.03219184+0.j, 0.02969543+0.j, 0.02255606+0.j, 0.01660086+0.j])

description:
Changed syntax of constant vector and tensor functions to use Array.
The following are equivalent and generalizes in the obvious way:
Function(mesh, 2, 0.0);
Array<real> values(0.0, 0.0);
Function(mesh, values);
Array<uint> shape(2);
Array<real> values(0.0, 0.0);
Function(mesh, shape, values);
In Python, the typemaps doesn't seem to pick up lists,
so the corresponding syntax there is currently:
f = Function(mesh, 2, 0.0)
f = Function(mesh, ArrayDouble(0.0, 0.0))
f = Function(mesh, ArrayUInt(2), ArrayDouble(0.0, 0.0))
