Blitz Support : |

Hi all,
I was trying to put some shape checks into a program, and I ran into the
following problem. This code (U and T are blitz Arrays ):
cout << U.shape()(Range(1,toEnd)) << endl;
cout << T.shape()(Range(fromStart,toEnd-1)) << endl;
Does not work. I basically need to check (using python syntax) that
U.shape[1:] == T.shape[:-1]
and I was trying to put the above C++ into an assert() call. But it seems
that TinyVectors (which .shape() returns) do not support indexing via range
objects. Is this a fundamental limitation imposed by performance
considerations? If so, in order to perform the above checks, do I need to
simply write a loop by hand, or is there any way to do it using the Blitz
array syntax?
Thanks in advance for any help,
Fernando.
