# triangle

An enumeration that specifies which triangle unit-triangular, triangular, and symmetric matrices need to use.

## Declaration

```swift
var triangle: SparseTriangle_t { get set }
```

## Discussion

Discussion If kind is SparseOrdinary, this operation ignores this propoerty. Otherwise, it indicates which triangle (SparseUpperTriangle or SparseLowerTriangle) represents the matrix.
