# SparseSolve(_:_:)

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

## Declaration

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

## Parameters

- `Subfactor`: The Subfactor in Subfactor * X = B that doc://com.apple.accelerate/documentation/Accelerate/SparseCreateSubfactor(_:_:)-4renf returns.
- `XB`: On input, the vector B. On return, the vector X overwrites it.
