public static long vectorBytesForLengthDataType(long length,
                                                int dataType)

Return the recommended stride, in bytes, to be used for an array of vectors of a given length.

To achieve best performance the optimal stride between vectors within an array of vectors is not necessarily equivalent to the number of elements per vector. This method returns the stride, in bytes, which gives best performance for a given vector length. Using this stride to construct your array is recommended, but not required (provided that the stride used is still large enough to allocate a full vector of data).

Parameters:

length - The number of elements in a single vector.

dataType - The type of vector data values.

vectorDescriptorWithLengthDataType

public static MPSVectorDescriptor vectorDescriptorWithLengthDataType(long length,
                                                                     int dataType)

Create a MPSVectorDescriptor with the specified length and data type.

Use this function for creating a descriptor of a MPSVector object containing a single vector.

Parameters:

length - The number of elements in a single vector.

dataType - The type of the data to be stored in the vector.

vectorDescriptorWithLengthVectorsVectorBytesDataType

public static MPSVectorDescriptor vectorDescriptorWithLengthVectorsVectorBytesDataType(long length,
                                                                                       long vectors,
                                                                                       long vectorBytes,
                                                                                       int dataType)

Create a MPSVectorDescriptor with the specified length and data type.

For performance considerations the optimal stride between vectors may not necessarily be equal to the vector length. The MPSVectorDescriptor class provides a method which may be used to determine this value, see the vectorBytesForLength API.

Parameters:

length - The number of elements in a single vector.

vectors - The number of vectors in the MPSVector object.

vectorBytes - The number of bytes between starting elements of consecutive vectors.

dataType - The type of the data to be stored in the vector.

vectors

public long vectors()

[@property] vectors

The number of vectors.
