# 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, _ B: DenseMatrix_Complex_Float, _ X: DenseMatrix_Complex_Float)
```

## Parameters

- `Subfactor`: (Input) The subfactor to solve a system involving, as returned by SparseCreateSubfactor().
- `B`: (Input) The right-hand sides B. If Subfactor is m x n, then B must have dimension m x nrhs, where nrhs is the number of right-hand sides.
- `X`: (Output) The solutions X. If Subfactor is m x n, and B is m x nrhs, then X must have dimension n x nrhs.
