#include <array_ops.h> नए बैच वाले विकर्ण मानों के साथ बैचयुक्त मैट्रिक्स टेंसर लौटाता है।
सारांश
input और diagonal देखते हुए, यह ऑपरेशन input के समान आकार और मान के साथ एक टेंसर लौटाता है, अंतरतम मैट्रिक्स के निर्दिष्ट विकर्णों को छोड़कर। इन्हें diagonal में मानों द्वारा अधिलेखित कर दिया जाएगा।
input में r+1 आयाम हैं [I, J, ..., L, M, N] । जब k अदिश या k[0] == k[1] , diagonal r आयाम होता है [I, J, ..., L, max_diag_len] । अन्यथा, इसके r+1 आयाम हैं [I, J, ..., L, num_diags, max_diag_len] । num_diags विकर्णों की संख्या है, num_diags = k[1] - k[0] + 1 । max_diag_len श्रेणी में सबसे लंबा विकर्ण है [k[0], k[1]] , max_diag_len = min(M + min(k[1], 0), N + min(-k[0], 0))
आउटपुट [I, J, ..., L, M, N] आयामों के साथ रैंक k+1 का एक टेंसर है। यदि k अदिश राशि है या 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 अन्यथा,
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 जहां
d = n - m ,
diag_index = k[1] - d , और
index_in_diag = n - max(d, 0) + offset ।
offset शून्य है, सिवाय इसके कि जब विकर्ण का संरेखण दाईं ओर हो।
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 जहां
diag_len(d) = min(cols - max(d, 0), rows + min(d, 0)) उदाहरण के लिए:

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.

These will be overwritten by the values in `diagonal`.\n\n`input` has `r+1` dimensions `[I, J, ..., L, M, N]`. When `k` is scalar or `k[0] == k[1]`, `diagonal` has `r` dimensions `[I, J, ..., L, max_diag_len]`. Otherwise, it has `r+1` dimensions `[I, J, ..., L, num_diags, max_diag_len]`. `num_diags` is the number of diagonals, `num_diags = k[1] - k[0] + 1`. `max_diag_len` is the longest diagonal in the range `[k[0], k[1]]`, `max_diag_len = min(M + min(k[1], 0), N + min(-k[0], 0))`\n\nThe output is a tensor of rank `k+1` with dimensions `[I, J, ..., L, M, N]`.
