# Vec

Abstract PETSc vector object. Used for holding solutions and right-hand sides for linear systems, nonlinear systems, and time integrators

## Synopsis

    typedef struct _p_Vec *Vec;

## Note

Internally the actual vector representation is generally a simple array but most PETSc code can work on other representations through this abstraction
