Your welcome.  Kudos for developing this library, it looks impressive.  One of 
my main frustrations with C++ has been the complete absense of any decent 
array handling.  (std::valarray doesn't count)....

One of the reasons I have started investigating this library is in relation to 
interfacing with MATLAB.

The concept of storage orders seems to be almost what is needed, but at the 
same time I doubt it will work.  I have started using MATLAB for the 
convenience of prototyping, data analysis etc.  Unfortunately the part of the 
MATLAB API I am using deals with complex numbers using seperate arrays for 
the real and imaginary parts, rather than one array of (say) complex<double>.

The library requires:

	double* realPart;
	double* imagPart;

Whereas a typical array (even in Blitz++) would be

	Array<complex<double>,2> A(2,2);

A pointer to which is given by:
	complex<double>* complexArray=A.data();

Is there any way (no matter how contrived), that pointers to the real and 
imaginary parts can be returned such that 

	realPart++;  imagPart++;

point to the next real and imaginary double?

If this question is better suited to a discussion board please advise me where 
it should go...

Thanks,
