# SparseSolve(_:_:)

Solve the equation Subfactor * X = B for the matrix X of complex float values, in place.

## Declaration

```swift
func SparseSolve(_ Subfactor: SparseOpaqueSubfactor_Complex_Float, _ XB: DenseMatrix_Complex_Float)
```

## Parameters

- `Subfactor`: (Input) The subfactor to solve a system involving, as returned by SparseCreateSubfactor().
- `XB`: (Input/Output) On input, the matrix B. On return it is overwritten with the matrix X. If Subfactor is m x n, then XB must have dimension k x nrhs, where k = max(m, n) and nrhs is the number of right-hand sides. If m != n, then only the first min(m,n) entries are used for input or output as approriate.
