my matrix is too big.
EIGS : fuction to find eigenvector
I want to call EIGS more faster. matlab interpreter is weak at iteration ("for" loop). I know that C-MEX is faster than matlab language.
If I code EIGS by C-MEX, It would be faster than EIGS of matlab? or if I call EIGS, does it already be compiled?? so no interpreter?
question) 1) I want to find eigenvector very fast. ( my matrix is too big) how I do that?
2) is there any library coded by C-MEX that find eigenvector???
plz help me I'll appreciate it

Hi,
eigs already uses Arpack library functions for computing. Therefore: no, coding as a C-MEX function would not make it faster.
