Boost::multi_array performance question

Question

I am trying to compare the performance of boost::multi_array to native dynamically allocated arrays, with the following test program:

#include 

        

Answer 1

I modified the above code in visual studio 2008 v9.0.21022 and applied the container routines from the Numerical Recipe routines for C and C++

http://www.nrbook.com/nr3/ using their licensed routines dmatrix and MatDoub respectively

dmatrix uses the out of date syntax malloc operator and is not recommended... MatDoub uses the New command

The speed in seconds are in Release version:

Boost: 0.437

Native: 0.032

Numerical Recipes C: 0.031

Numerical recipes C++: 0.031

So from the above blitz looks like the best free alternative.
