Detailed Description

template<class T>
class ebl::idxiter< T >

idxiter allows to iterate over all elements of an idx. Although it can be used directly, it is easier to use it with the idx_aloopX macros. Example: idxiter<double> idx; for ( idx.init(m); idx.notdone(); idx.next() ) { printf("%g ",*idx); } Here is an example that uses the aloop macro to fill up an idx with numbers corresponding to the loop index: idxiter<double> idx; idx_aloop_on(idx,m) { *idx = idx.i; } At any point during the loop, the indices of the element being worked on is stored in idx.d[k] for k=0 to idx.order()-1.
