# solveWorkspaceRequiredPerRHS

The required size of the per-right-hand-side workspace for a call to a sparse solve function.

## Declaration

```swift
var solveWorkspaceRequiredPerRHS: Int
```

## Discussion

Discussion The required size of workspace in bytes for a call to a sparse solve function is solveWorkspaceRequiredStatic + nrhs * solveWorkspaceRequiredPerRHS where nrhs is the number of right-hand-side vectors.
