lookup values on array based on sequences 
Lookup the values of input array based on sequences. 
- Parameters
- 
  
    | [out] | out | output array containing values indexed by the sequences |  | [in] | in | is the input array |  | [in] | ndims | is the number of sequences provided |  | [in] | index | is an array of sequences |  
 
 
 
Indexing an array using af_seq, or af_array. 
Generalized indexing function that accepts either af_array or af_seq along a dimension to index the input array and create the corresponding output array
- Parameters
- 
  
    | [out] | out | output array containing values at indexed by the sequences |  | [in] | in | is the input array |  | [in] | ndims | is the number of af_index_t provided |  | [in] | indices | is an array of af_index_t objects |  
 
 
 
Lookup the values of input array based on index. 
- Parameters
- 
  
    | [out] | out | output array containing values at locations specified by index |  | [in] | in | is input lookup array |  | [in] | indices | is lookup indices |  | [in] | dim | specifies the dimension for indexing |  
 
 
 
Copy the values of an input array based on index. 
- Parameters
- 
  
    | [out] | dst | The destination array |  | [in] | src | The source array |  | [in] | idx0 | The first index |  | [in] | idx1 | The second index (defaults to af::span) |  | [in] | idx2 | The third index (defaults to af::span) |  | [in] | idx3 | The fourth index (defaults to af::span) |  
 
- Examples: 
- blas.cpp, and histogram.cpp.
