The SAMRAI vector class wraps a collection of patch data components defined over multiple levels in an AMR hierarchy so that the data may be manipulated as though it is a single vector. Also, included are classes which provide vector kernels to the PETSc and Sundials solver packages. Currently, vector interfaces are provided for real-valued vectors only (i.e., where the data is either type double or float). If the need for complex-valued vectors arises (e.g., PETSc supports complex vectors), they can be easily added. Presently, the Sundials vector interface supports only double-valued vectors. The abstract classes that define the interfaces to the PETSc and Sundials packages are includes in the SAMRAI source subdirectories "petsc" and "cvode::trio/vector", respectively. The classes which perform the actual numerical operations used in the vector kernels are found in the "Mathematical Operations" package.
