There are specialized, more efficient versions for two and three
dimensional arrays. They are as follows.
int vc_Index2(vc_handle, U, U)
Specialized version of vc_Index() where the two U parameters are
the indices in a two dimensional array.
int vc_Index3(vc_handle, U, U, U)
Specialized version of vc_Index() where the two U parameters are
the indices in a three dimensional array.
U vc_mdaSize(vc_handle, U)
Returns the following:
• If the U type parameter has a value of 0, it returns the number of
indices in the multi-dimensional array.
