Re: [Vxl-users] a general question about VXL

[Shoujie H. <mai...@gm...>]

Hi, Lan,

Thank you very much for your quick and informative response.
LAPACK, BLAS, and MINPACK are all Fortran based, am I right?
Should I install those Fortran compiled libraries separately before
installing or building VXL?
Is there any website comparing these libraries? I am more interested in the
coverage of their functionalities. For example, LAPACK and BLAS are more
linear algebra (vector, matrix computation), etc.
We probably need a table if not yet to give a summary about these libraries.

Thanks again for the information you provided about VXL.
