I mean in solving Numerical PDE the matrix is usually quiet big but sparse. the normal “/” seems to use LU decomposition which makes a saprse matrix become two dense and will outofmemory qiuckly.

[image] Lyupinpin: It is solving a three dimensional PDE and N is the how much part we divide the PDE in different dimension. When N=30 it warks well, but when N=100 […] when the size of the matrix increase it will Outofmemory You should realize that there is an intrinsic limitation of sparse…

Does julia has a Package designed to / for sparse matrix

A minimal example would be kind on your helpers. Have a read through Please read: make it easier to help you, in particular point 4.
