<div>Hello PETSc developers,</div>
<div> </div>
<div>I understand PETSc replaces the scalar data type with a complex type for all solvers, and that configuring with fortran kernels improves performance, however it is unclear to me why in .../ksp/ksp/examples/tutorials/ex11.c the dimension of the matrix is set to: dim = n*n. If the matrix entries are stored in CSR can one interpret a matrix with complex entries as a vector where each entry is complex-valued or does this approach create 'two' matrices one with the real value the other with the imaginary part?</div>
<div> </div>
<div>Thanks.</div>
