eigenvalue decomposition using Matlab
Im conducting dimensioality reduction of a square matrix A,my issue now is that I have problem computing eigvalue decomposition of a 13000 x 13000 matrix A,ie [v d]=eigs(A) bcos its a sparse matrix, I get 'out of memory error' using a 4GB RAM,now Im convinced is not my pc problem, since the memory is not used up when eigs command is run. the help I saw online had to do with ARPACK, I checked the recommended site, but there were a lot of files there, dont know which to download, also did not understand how to use it with Matlab, another say use numerical methods, but I dont know which specific one to use. Please any solution is welcome.
