class RTensor x i e m => MTensor x i e m where

Source

Class for modifiable mutable tensors.

Methods

getMaxSize :: x e -> m Int

Source

Get the maximum number of elements that can be stored in the tensor.

setZero :: x e -> m ()

Source

Sets all stored elements to zero.

setConstant :: e -> x e -> m ()

Source

Sets all stored elements to the given value.

canModifyElem :: x e -> i -> m Bool

Source

True if the value at a given index can be changed

unsafeWriteElem :: x e -> i -> e -> m ()

Source

Set the value of the element at the given index, without doing any range checking.

unsafeModifyElem :: x e -> i -> (e -> e) -> m ()

Source

Modify the value of the element at the given index, without doing any range checking.

modifyWith :: (e -> e) -> x e -> m ()

Source

Replace each element by a function applied to it

Instances

writeElem :: (MTensor x i e m, Show i) => x e -> i -> e -> m ()

Source

Set the value of the element at the given index.

modifyElem :: (MTensor x i e m, Show i) => x e -> i -> (e -> e) -> m ()

Source

Update the value of the element at the given index.
