Class MPSMatrixSolveLU

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSMatrixSolveLU
extends MPSMatrixBinaryKernel
    MPSMatrixSolveLU [@dependency] This depends on Metal.framework. A kernel for computing the solution of a linear system of equations using the LU factorization resulting from a MPSMatrixDecompositionLU kernel. A MPSMatrixSolveLU finds the solution matrix to the system: op(A) * X = B Where op(A) is A**T or A. B is the array of right hand sides for which the equations are to be solved. X is the resulting matrix of solutions.

        Encode a MPSMatrixSolveLU kernel into a command Buffer. This function encodes the MPSMatrixSolveLU object to a valid command buffer. sourceMatrix should contain the lower and upper triangular factors of A as results from a previous execution of MPSMatrixDecompositionLU. pivotIndices is an array of pivots resulting from a previous execution of MPSMatrixDecompositionLU. rightHandSideMatrix and solutionMatrix must be large enough to hold a matrix of size order x numberOfRightHandSides starting at secondarySourceMatrixOrigin and resultMatrixOrigin respectively. sourceMatrix must be at least size order x order starting at primarySourceMatrixOrigin.
        Parameters:
        commandBuffer - A valid MTLCommandBuffer to receive the encoded filter
        sourceMatrix - A valid MPSMatrix containing the source matrix in factored form as returned by a previous successful execution of a MPSMatrixDecompositionLU kernel.
        rightHandSideMatrix - A valid MPSMatrix containing the right hand side values.
        pivotIndices - A valid MPSMatrix which contains the pivot indices as returned by a previous successful execution of a MPSMatrixDecompositionLU kernel.
        solutionMatrix - A valid MPSMatrix to contain the result.

      • initWithCoderDevice

        public MPSMatrixSolveLU initWithCoderDevice​(NSCoder aDecoder,
                                            java.lang.Object device)
        Description copied from class: MPSKernel
        NSSecureCoding compatability While the standard NSSecureCoding/NSCoding method -initWithCoder: should work, since the file can't know which device your data is allocated on, we have to guess and may guess incorrectly. To avoid that problem, use initWithCoder:device instead.
        Overrides:
        initWithCoderDevice in class MPSMatrixBinaryKernel
        Parameters:
        aDecoder - The NSCoder subclass with your serialized MPSKernel
        device - The MTLDevice on which to make the MPSKernel
        Returns:
        A new MPSKernel object, or nil if failure.

      • initWithDevice

        public MPSMatrixSolveLU initWithDevice​(java.lang.Object device)
        Description copied from class: MPSKernel
        Standard init with default properties per filter type
        Overrides:
        initWithDevice in class MPSMatrixBinaryKernel
        Parameters:
        device - The device that the filter will be used on. May not be NULL.
        Returns:
        a pointer to the newly initialized object. This will fail, returning nil if the device is not supported. Devices must be MTLFeatureSet_iOS_GPUFamily2_v1 or later.

        public MPSMatrixSolveLU initWithDeviceTransposeOrderNumberOfRightHandSides​(MTLDevice device,
                                                                           boolean transpose,
                                                                           long order,
                                                                           long numberOfRightHandSides)
        Initialize an MPSMatrixSolveLU object on a device
        Parameters:
        device - The device on which the kernel will execute.
        transpose - A boolean value which indicates if the source matrix should be used in transposed form.
        order - The order of the source matrix and the number of rows in the solution and right hand side matrices.
        numberOfRightHandSides - The number of columns in the solution and right hand side matrices.
        Returns:
        A valid MPSMatrixSolveLU object or nil, if failure.

        This property must return YES on all classes that allow secure coding. Subclasses of classes that adopt NSSecureCoding and override initWithCoder: must also override this method and return YES. The Secure Coding Guide should be consulted when writing methods that decode data.
