c++ Programming Glossary: zlengthFlattening a 3D array in c++ for use with MPI http://stackoverflow.com/questions/16288944/flattening-a-3d-array-in-c-for-use-with-mpi the index calculation e.g. #define ARR A i j k A i ylength zlength j zlength k ARR myarray i j k ARR myarray i 1 j k ARR myarray.. calculation e.g. #define ARR A i j k A i ylength zlength j zlength k ARR myarray i j k ARR myarray i 1 j k ARR myarray i j 1 k.. of fixed leading dimensions e.g. whatever x ylength x zlength . Much better way to do it is to use so called dope vectors...
