Hi, users,
I have a problem with calculating the eigenvalue problem using the eig().
The array I want to calculate is about 5000*5000 but, the array is very
sparse.
At each row it has only 3 non-zero items, and the matrix is diagonal.
I have to solve eigenvalue problem, but it takes very long time.
How can I do?
I try to use sparse matix in Scipy, but eig() function doent' work with
sparse_matrix.
Please help me~!
Thank you.
