Hello I am writing to you to ask some technical problems that I am dealing with the use of PETSc.
The problem that I am facing is the following: I have defined a vector in Petsc which was created with VecCreateMPI. After that, I read this vector from an external file with a PETSc viewer. So if the initial vector is V with size N, I want to obtain a smaller vector U with size M, where M<N. I have an array of integers that are the indexes of V that I want to pass to U. How can I do this?
