Declaring an uBLAS Matrix

Question

I am not sure how to use the uBLAS interface provided by FEniCS. I.e. When I try

import dolfin
a = dolfin.uBLASMatrix(2,2)

I get the following message

AttributeError: 'module' object has no attribute 'uBLASMatrix'

Is there something I forgot to install?

Answer 1

Try this instead

a = dolfin.uBLASDenseMatrix(2,2)

If you are unsure which backends you have do

list_linear_algebra_backends()

Thanks, this worked
