# userFactorStorage

A Boolean value that indicates whether user-provided storage backs this object.

```
var userFactorStorage: Bool
```

## Discussion

If <doc://com.apple.documentation/documentation/Swift/true>, the user must free factor storage after all references finish (though [`SparseCleanup(_:)`](/documentation/Accelerate/SparseCleanup(_:)-3cnxt) still frees any additional allocated storage due to pivoting).
