:orphan: # VecPointwiseDivide Computes the component-wise division `w[i] = x[i] / y[i]`. ## Synopsis ``` #include "petscvec.h" PetscErrorCode VecPointwiseDivide(Vec w, Vec x, Vec y) ``` Logically Collective ## Input Parameters - ***x -*** the numerator vector - ***y -*** the denominator vector ## Output Parameter - ***w -*** the result ## Note Any subset of the `x`, `y`, and `w` may be the same vector. ## See Also [](ch_vectors), `Vec`, `VecPointwiseMult()`, `VecPointwiseMax()`, `VecPointwiseMin()`, `VecPointwiseMaxAbs()`, `VecMaxPointwiseDivide()` ## Level advanced ## Location src/vec/vec/interface/vector.c ## Examples src/ksp/ksp/tutorials/ex72.c
