Eliminate Dirichlet boundary conditions from matrix

Parameters
|
||||
----------
|
||||
dirichletbc : array [dim x nnodes]
|

I, J, V : sparse matrix arrays

Notes

-----
|

pros:
|
||||
- matrix assembly remains positive definite
|

cons:
|
||||
- maybe inefficient because of extra sparse matrix operations. (It's hard to remove stuff from sparse matrix.)
|
||||
- if u != 0 in dirichlet boundary requires extra care
|
||||
|
||||
Raises
|
||||
------
|
||||
Exception, if displacement boundary conditions given, i.e.
|

DX=2 for some node, for example.
