- Method Detail
  - solveSparse
```
void solveSparse(S B,
                 S X)
```
    Solve against sparse matrices. A*X=B. In most situations its more desirable to solve against a dense matrix because of fill in.
    
    Parameters:
    
    B - Input. Never modified.
    
    X - Output. Never modified.
  - setStructureLocked
```
void setStructureLocked(boolean locked)
```
    Save results from structural analysis step. This can reduce computations of a matrix with the exactly same non-zero pattern is decomposed in the future. If a matrix has yet to be processed then the structure of the next matrix is saved. If a matrix has already been processed then the structure of the most recently processed matrix will be saved.
  - isStructureLocked
```
boolean isStructureLocked()
```
    Checks to see if the structure is locked.
    
    Returns:
    
    true if locked or false if not locked.
