examples with clapack for a beginner

Postby jimbakl » Sat Nov 19, 2011 6:48 am

Hello everyone... I'm newbie better not newbie, but this is my 1st touch at this kind of programming. So now i must use this library solving a lot of linear algebra problems, like,
B '
B ' * w=c;
matrix transpose;
inverse of matrices; multiplication,

this is what i must know to solve my problems..
for small matrices 2*2 or 3*3 i can fix these, but now the problem contain matrices with 100000000*10000000
and i MUST use C, despite i know matlab...
i have spent about a week to install all the requirement stuff and know its time to learn about it.
Could you send me a file? or a link? where referred understandable examples for my case....
Or whatever you think that is going to help me...
Thanks you in advance!!!

Best is to go through the LAPACK user guide. http://www.netlib.org/lapack/lug/
For simple matrix operation, you will just need the BLAS. See http://en.wikipedia.org/wiki/Basic_Linear_Algebra_Subprograms
LAPACK is for dense matrix, the size of your matrix seems very huge for a dense matrix.
