Class MPSNDArrayMatrixMultiplication

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSNDArrayMatrixMultiplication
extends MPSNDArrayMultiaryKernel
    MPSNDArrayMatrixMultiplication [@dependency] This depends on Metal.framework. A matrix multiplication kernel operating on MPSNDArray objects. A MPSNDArrayMatrixMultiplication object computes, for each 2-D matrix within a 4-D MPSNDArray object: D = alpha * A * B + beta * C A, B, C, and D are matrices which are represented by objects stored in the two most major dimensions of the MPSNDArray. alpha and beta are scalar values (of the same data type as values of D and C) which are applied as shown above. If an input's 3rd or 4th dimension is 1 its data will be broadcast as appropriate to the remaining input's 3rd or 4th dimension respectively.
