Module tornado.api

Package uk.ac.manchester.tornado.api.types.matrix

Class Matrix2DFloat

java.lang.Object

uk.ac.manchester.tornado.api.types.matrix.Matrix2DFloat

All Implemented Interfaces:

Serializable, PrimitiveStorage<FloatBuffer>, TornadoMatrixInterface<FloatBuffer>

public final class Matrix2DFloat
extends Object
implements TornadoMatrixInterface<FloatBuffer>

Matrix2DFloat relies on preview features of the Java platform:

• Matrix2DFloat refers to one or more preview APIs: MemorySegment.

Programs can only use Matrix2DFloat when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
