发帖数: 2334 | 1 does anybody have numerical recipe in c++? I need the subroutine to solve
A x = b with A being symmetric.
I tried to use clapack. The software won't allow me to call the BLAS fortran
subroutines. Thanks ahead. |

I suggest that, try IT++, it is for c++, very easy to us, and has almost every
thing for matrix calculations.

发帖数: 2334 | 6 Thanks. I am using TNT from netlib. It seems good. It does not fail even
for singular A.
BTW, what is IT++?

发帖数: 100 | 7 IT++ is a C++ library of mathematical, signal processing, speech processing,
and communications classes and functions.
http://itpp.sourceforge.net/
It can deal with matrix calculations very simple. Such:
M.eig() will give you the eigenvalues of M.
you can look the website.
I used TNT before, not bad. :)

我觉得很多时候GSL比numerical recipe好用，而且是GPL的

发帖数: 2334 | 9 what is GSL? I never use C++ to write any program for numerical computations.
Tired of Fortran77. Wanna try C++ for next project.
