# SparseSolve(_:_:_:)

Solves the equation Subfactor * X = B in place for the vector of single-precision values X.

## Declaration

```swift
func SparseSolve(_ Subfactor: SparseOpaqueSubfactor_Float, _ B: DenseVector_Float, _ X: DenseVector_Float)
```

## Parameters

- `Subfactor`: The Subfactor in Subfactor * X = B that doc://com.apple.accelerate/documentation/Accelerate/SparseCreateSubfactor(_:_:)-4renf returns.
- `B`: The vector B.
- `X`: The vector X.
