Hello Everyone,
I have a question about LU factorization.
I understand that LU factorization provides an upper and lower traingular matrices of matrix A. In matlab, a large matrix was generated, and we plotted the sparsity of A and then the sparsity of L+U and it was less sparse.
My question is:
Why would we want to do this? Is it used to just save time when finding the inverse of a matrix?
