Class MPSNDArrayGather

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSNDArrayGather
extends MPSNDArrayBinaryKernel
    MPSNDArrayGather [@dependency] This depends on Metal.framework. Applies a gather operation along a given axis. The encoded primary source array contains the data and the secondary array is a 1-D MPSNDArray containing the indices. For each dimension other than axis result[i] = source[i]; 0 <= i < array slice length along dimension Along the specified axis result[i] = source[indices[i]]; 0 <= i < number of indices API-Since: 13.0
