# trilInPlace

[common]\
fun [trilInPlace](trilInPlace.md)(self: [Tensor](../Tensor/index.md), diagonal: [Long](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-long/index.html) = 0): [Tensor](../Tensor/index.md)

`trilInPlace(self: Tensor, diagonal: Long = 0L)`: the `tril_` operator. In-place `tril`: zeroes the upper triangle through `self`; same arguments and error conditions as `tril()`. A view input writes through its base storage. Returns `self` under the value surface, `Result<void>` under the `Result` surface; `CLIKART_CHECK` is the mode-stable spelling. Writes through `self` and returns it, so calls chain.
