Issue on page /chapter1/complex_mode.html #129
Description
After reading the tutorial, I understand that Docker has the ability to switch between float64 and complex128. However, I am unsure of how to do this on Ubuntu 22.04.
To begin, I ran the command dpkg -l | grep petsc and obtained a list of packages.
ii libpetsc-complex3.15:amd64 3.15.5+dfsg1-1build2 amd64 Shared libraries for version 3.15 of PETSc with Complex Numbers
ii libpetsc-real3.15:amd64 3.15.5+dfsg1-1build2 amd64 Shared libraries for version 3.15 of PETSc
ii libpetsc-real3.15-dev:amd64 3.15.5+dfsg1-1build2 amd64 Static libraries, shared links, header files for PETSc
ii libpetsc3.15-dev-common 3.15.5+dfsg1-1build2 all Common header and support dev files for PETSc
ii libpetsc3.15-dev-examples 3.15.5+dfsg1-1build2 all Static libraries, shared links, header files for PETSc
ii python-petsc4py-doc 3.15.1-2build1 all Python bindings for PETSc libraries: documentation and examples
ii python3-petsc4py 3.15.1-2build1 all Python 3 bindings for PETSc libraries
ii python3-petsc4py-complex 3.15.1-2build1 all Python 3 bindings for PETSc libraries (complex numbers)
ii python3-petsc4py-complex3.15 3.15.1-2build1 amd64 Python 3 bindings for PETSc 3.15 libraries (complex numbers)
ii python3-petsc4py-real 3.15.1-2build1 all Python 3 bindings for PETSc libraries (real numbers)
ii python3-petsc4py-real3.15 3.15.1-2build1 amd64
From this list, I can see that pyhon3-petsc4py-complex is already installed. But the current scalar type in python3 is still <class 'numpy.float64'>.
What steps should I take next to switch between float64 and complex128?
