eigen value for very larger matrix

I am trying to use eigs to solve the eigen value of a very large
matrix.
But I get a "out of memory" problem.

Does anyone know how to deal with this problem?

The following is error message.

[b_1giy,cc_1giy]=Anm_70S_two_nodes('./RNA_data_set/1GIY.pdb',1.0,15,24
,0.00001);
??? Error using ==> ctranspose
