public class MPSMatrixDecompositionCholesky
extends MPSMatrixUnaryKernel

MPSMatrixDecompositionCholesky

[@dependency] This depends on Metal.framework.

A kernel for computing the Cholesky factorization of a matrix.

A MPSMatrixDecompositionLU object computes one of the following factorizations of a matrix A:

A = L * L**T A = U**T * U

A is a symmetric positive-definite matrix for which the factorization is to be computed. L and U are lower and upper triangular matrices respectively.

Encode a MPSMatrixDecompositionCholesky kernel into a command Buffer.

This function encodes the MPSMatrixDecompositionCholesky object to a valid command buffer.

If during the factorization a leading minor of the matrix is found to be not positive definite, MPSMatrixDecompositionNonPositiveDefinite will be returned in the provided status buffer. Previously computed pivots and the non positive pivot are written to the result, but the factorization does not complete. The data referenced by the MTLBuffer is not valid until the command buffer has completed execution. If the matrix return status is not desired NULL may be provided.

If the return status is MPSMatrixDecompositionStatusSuccess, resultMatrix contains the resulting factors in its lower or upper triangular regions respectively.

This kernel functions either in-place, if the result matrix completely aliases the source matrix, or out-of-place. If there is any partial overlap between input and output data the results are undefined.

Parameters:

commandBuffer - A valid MTLCommandBuffer to receive the encoded filter

sourceMatrix - A valid MPSMatrix containing the source data. Must have enough space to hold a order x order matrix.

resultMatrix - A valid MPSMatrix to contain the result. Must have enough space to hold a order x order matrix.

status - A MTLBuffer which indicates the resulting MPSMatrixDecompositionStatus value.

hash_static

init

public MPSMatrixDecompositionCholesky init()

Overrides:

init in class MPSMatrixUnaryKernel

initWithCoder

public MPSMatrixDecompositionCholesky initWithCoder(NSCoder aDecoder)

Description copied from interface: NSCoding

NS_DESIGNATED_INITIALIZER

Specified by:

initWithCoder in interface NSCoding

Overrides:

initWithCoder in class MPSMatrixUnaryKernel

initWithCoderDevice

public MPSMatrixDecompositionCholesky 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 MPSMatrixUnaryKernel

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 MPSMatrixDecompositionCholesky initWithDevice(java.lang.Object device)

Description copied from class: MPSKernel

Standard init with default properties per filter type

Overrides:

initWithDevice in class MPSMatrixUnaryKernel

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.

initWithDeviceLowerOrder

public MPSMatrixDecompositionCholesky initWithDeviceLowerOrder(MTLDevice device,
                                                               boolean lower,
                                                               long order)

Initialize an MPSMatrixDecompositionCholesky object on a device

Parameters:

device - The device on which the kernel will execute.

lower - A boolean value indicating if the lower triangular part of the source matrix is stored. If lower = YES the lower triangular part will be used and the factor will be written to the lower triangular part of the result, otherwise the upper triangular part will be used and the factor will be written to the upper triangular part.

order - The number of rows and columns in the source matrix.

Returns:

A valid MPSMatrixDecompositionCholesky object or nil, if failure.

public boolean _supportsSecureCoding()

Description copied from interface: NSSecureCoding

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.
