Hello all! 

I can't find the legal way to assign the one matrix_range to another matrix_range.

matrix_range<M> A;
matrix_range<M> B;

all assign operation perfrom data copy from A data view to B data view.

But i want to assign in manner of 

A.assign( B )  that not change the data of "M" but the A data view will point in the same data that point B.

Thanks!
