tensor akışı:: işlem:: MatrixSetDiagV3

#include <array_ops.h>

Yeni toplu çapraz değerlere sahip toplu matris tensörünü döndürür.

Özet

input ve diagonal verildiğinde, bu işlem, en içteki matrislerin belirtilen köşegenleri dışında, input ile aynı şekil ve değerlere sahip bir tensör döndürür. Bunların üzerine diagonal değerler yazılacaktır.

input r+1 boyutu vardır [I, J, ..., L, M, N] . k skaler olduğunda veya k[0] == k[1] olduğunda, diagonal r boyutlara sahiptir [I, J, ..., L, max_diag_len] . Aksi takdirde, r+1 boyutları vardır [I, J, ..., L, num_diags, max_diag_len] . num_diags köşegenlerin sayısıdır, num_diags = k[1] - k[0] + 1 . max_diag_len [k[0], k[1]] aralığındaki en uzun köşegendir max_diag_len = min(M + min(k[1], 0), N + min(-k[0], 0))

Çıkış [I, J, ..., L, M, N] boyutlarına sahip k+1 dereceli bir tensördür. Eğer k skaler veya k[0] == k[1] : 

output[i, j, ..., l, m, n]
  = diagonal[i, j, ..., l, n-max(k[1], 0)] ; if n - m == k[1]
    input[i, j, ..., l, m, n]              ; otherwise

Aksi takdirde, 

output[i, j, ..., l, m, n]
  = diagonal[i, j, ..., l, diag_index, index_in_diag] ; if k[0] <= d <= k[1]
    input[i, j, ..., l, m, n]                         ; otherwise
 burada d = n - m , diag_index = k[1] - d ve index_in_diag = n - max(d, 0) + offset .

köşegen hizalamasının sağa olması dışında offset sıfırdır.

offset = max_diag_len - diag_len(d) ; if (`align` in {RIGHT_LEFT, RIGHT_RIGHT}
                                           and `d >= 0`) or
                                         (`align` in {LEFT_RIGHT, RIGHT_RIGHT}
                                           and `d <= 0`)
         0                          ; otherwise
 burada diag_len(d) = min(cols - max(d, 0), rows + min(d, 0)) .

Arguments:
    
      
  • scope: A Scope object
    • 
      
  • input: Rank r+1, where r >= 1.
    • 
      
  • diagonal: Rank r when k is an integer or k[0] == k[1]. Otherwise, it has rank r+1. k >= 1.
    • 
      
  • k: Diagonal offset(s). Positive value means superdiagonal, 0 refers to the main diagonal, and negative value means subdiagonals. k can be a single integer (for a single diagonal) or a pair of integers specifying the low and high ends of a matrix band. k[0] must not be larger than k[1].
    • 
    

  
Optional attributes (see Attrs):
    
      
  • align: Some diagonals are shorter than max_diag_len and need to be padded. align is a string specifying how superdiagonals and subdiagonals should be aligned, respectively. There are four possible alignments: "RIGHT_LEFT" (default), "LEFT_RIGHT", "LEFT_LEFT", and "RIGHT_RIGHT". "RIGHT_LEFT" aligns superdiagonals to the right (left-pads the row) and subdiagonals to the left (right-pads the row). It is the packing format LAPACK uses. cuSPARSE uses "LEFT_RIGHT", which is the opposite alignment.

Returns:
    
      
  • Output: Rank r+1, with output.shape = input.shape.
