Hi,
I am trying to use common math library to solve largescale liner equation
with sparse structure. Use the SpareRealMatrix interface
and OpenMapRealMatrix implementation, I defined my matrix. Then using the LU
decomposition,
new LUDecompositionImpl(A).getSolver().solve(B)
I could find the solution. However, the LU based solution seems to be very
slow. I guess, it solves the sparse matrix as a full matrix.
Question
 Does the LUComposition implementation take full advantage of the sparse
matrix structure
 If yes, where I might be wrong?
I am using common math lib 2.1.
Thanks, Mike Zhou
