[petsc-users] Elementwise pow/exponential-function on PETSc-vectors and matrices

[Roland Richter]

Hei,

is there a function to square/cube etc. each element of a matrix or
vector in PETSc? It is rather useful for things like intensity
calculations (I = |E|^2), and should work also for distributed matrices.

Thanks!

Regards,
