Modifier and Type	Method	Description
`void`	`reset(MatrixStore<java.lang.Double> basis)`	Until this has been called there is an implicit assumption that the basis is the identity matrix.
`void`	`update(MatrixStore<java.lang.Double> basis, int col, SparseArray<java.lang.Double> values)`	Update the inverse to reflect a replaced column in the basis.

- Method Detail
  - reset
```
void reset(MatrixStore<java.lang.Double> basis)
```
    Until this has been called there is an implicit assumption that the basis is the identity matrix. update(MatrixStore, int, SparseArray) before this method has been called.
  - update
```
void update(MatrixStore<java.lang.Double> basis,
            int col,
            SparseArray<java.lang.Double> values)
```
    Update the inverse to reflect a replaced column in the basis.
    
    Parameters:
    
    basis - Full basis, with the column already exchanged.
    
    col - The index, of the column, that was exchanged.
    
    values - The (non zero) values of that column.
