class

`SushiBLAS::LogicOps`

Records comparisons, boolean combinations and truth tests of tensors.

Declared in: include/SushiBLAS/engine/logic/logic.hpp

Note

Every operand must have storage and dense strides, and the operands of one call must share one shape: the library does not broadcast.

Public member functions

explicit LogicOps(TaskRecorder &recorder) noexcept

Builds a view that records through recorder, which must outlive the view.

explicit LogicOps(Engine &engine) noexcept

Builds a view that records on engine's own graph.
