The output is:
<type 'numpy.float64'>

I installed petsc via macport and wrongly assumed complex number support would have been default.
I've just reinstalled petsc with it and it seems to be working.

thanks Lisandro !

Are you sure you built petsc4py with a PETSc build with complex scalars? Whats the output of "print(PETSc.ScalarType)" ?

    Hi,

    I am trying to solve a linear problem whose operator has complex
    coefficients via petsc4py
    but keep running into the following error:

      File
    
"/Users/aponte/Current_projects/people/kraig_marine/wd_response/solver/set_L.py",
    line 52, in set_L
        L.setValueStencil(row, col, value)
      File "PETSc/Mat.pyx", line 882, in
    petsc4py.PETSc.Mat.setValueStencil (src/petsc4py.PETSc.c:124785)
      File "PETSc/petscmat.pxi", line 1017, in
    petsc4py.PETSc.matsetvaluestencil (src/petsc4py.PETSc.c:31469)
      File "PETSc/arraynpy.pxi", line 140, in petsc4py.PETSc.iarray_s
    (src/petsc4py.PETSc.c:8811)
      File "PETSc/arraynpy.pxi", line 121, in petsc4py.PETSc.iarray
    (src/petsc4py.PETSc.c:8542)
    TypeError: can't convert complex to float

    The code looks like:

    for j in range(ys, ye):
        for i in range(xs, xe):
            row.index = (i, j, kx)
            row.field = 0
            col.index = (i, j, kx) col.field=0
            L.setValueStencil(row, col, 1j)

    Any idea about what am I doing wrong?

    cheers

    aurelien
