Hi everyone, I have a similarity matrix of image. It's symmetric, and sparse, large matrix. The computation of eigenvalues of this matrix takes too much time and memory. So I think parallelism of this computation will get better performance. But I don't know the way do that. Please give me any guide. Thanks!

Please post the code you are using and define "large" explicitly. Sometimes users of this forum use "large" for 20x20 matrices already.
