Class MPSMatrixSolveTriangular

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSMatrixSolveTriangular
extends MPSMatrixBinaryKernel
    MPSMatrixSolveTriangular [@dependency] This depends on Metal.framework. A kernel for computing the solution of a linear system of equations using a triangular coefficient matrix. A MPSMatrixSolveTriangular finds the solution matrix to the triangular system: op(A) * X = alpha * B or X * op(A) = alpha * B Where A is either upper or lower triangular and 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. API-Since: 11.0

        Encode a MPSMatrixSolveTriangular kernel into a command Buffer. This function encodes the MPSMatrixSolveTriangular object to a valid command buffer. rightHandSideMatrix and solutionMatrix must be large enough to hold at least order * numberOfRightHandSides values 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.
        rightHandSideMatrix - A valid MPSMatrix containing the right hand side values.
        solutionMatrix - A valid MPSMatrix to contain the result.

        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. API-Since: 11.0

        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.

        Initialize an MPSMatrixSolveTriangular object on a device This function initializes a MPSMatrixSolveTriangular object. It may allocate device side memory.
        Parameters:
        device - The device on which the kernel will execute.
        right - A boolean value which indicates if the coefficient matrix is multiplied on the left or right side of the solution. NO indicates the multiplication is on the left.
        upper - A boolean value which indicates if the source is lower or upper triangular. NO indicates that the coefficient matrix is lower triangular.
        transpose - A boolean value which indicates if the source matrix should be used in transposed form. NO indicates that the coefficient matrix is to be used normally.
        unit - A boolean value which indicates if the source matrix is unit triangular.
        order - The order of the source matrix and, if right == NO, the number of rows in the solution and right hand side matrices. If right == YES the number of columns in the solution and right hand side matrices.
        numberOfRightHandSides - If right == NO, the number of columns in the solution and right hand side matrices. The number of rows otherwise.
        alpha - A double precision value used to scale the right hand sides.
        Returns:
        A valid MPSMatrixSolveTriangular object or nil, if failure.
