First I have to thank you all for your replies. It is such a responsive group (I
hope my question was not too provocative though :) ).

I am trying to re-implement a project which uses a lot of linear algebra with
Boost, so please bear with me if my questions are very elementary. Here is my
curious question about the design of the numerical binding:

I thought that one design could be to provide functionalities of BLAS through
uBlas but only by turning ON/OFF a compiler flag. Let me explain what I mean by
an example: we have a command like prod in uBlas which is a uBlas implementation
of matrix-matrix product but if one wants to use BLAS, she has to use gemm
command. Why didn't you design it such that prod does both of them and a
compiler flag can decide which implementation (uBlas or BLAS) to be compiled?
 Again, I am sorry if it is such naive question, I am newbie to boost.
