টেনসরফ্লো :: অপস:: MatrixSetDiagV2
#include <array_ops.h> নতুন ব্যাচ করা তির্যক মান সহ একটি ব্যাচ করা ম্যাট্রিক্স টেনসর প্রদান করে।
সারাংশ
প্রদত্ত input এবং diagonal , এই ক্রিয়াকলাপটি input হিসাবে একই আকার এবং মান সহ একটি টেনসর প্রদান করে, ব্যতীত অন্তঃস্থ ম্যাট্রিক্সের নির্দিষ্ট কর্ণ ব্যতীত। এইগুলি diagonal মান দ্বারা ওভাররাইট করা হবে।
input r+1 মাত্রা রয়েছে [I, J, ..., L, M, N] । যখন k স্কেলার বা k[0] == k[1] , diagonal r মাত্রা থাকে [I, J, ..., L, max_diag_len] । অন্যথায়, এর r+1 মাত্রা আছে [I, J, ..., L, num_diags, max_diag_len] । num_diags হল কর্ণের সংখ্যা, num_diags = k[1] - k[0] + 1 । max_diag_len হল [k[0], k[1]] , max_diag_len = min(M + min(k[1], 0), N + min(-k[0], 0)) পরিসরের দীর্ঘতম কর্ণ
আউটপুট হল র্যাঙ্ক k+1 এর একটি টেনসর যার মাত্রা [I, J, ..., L, M, N] । k হলে স্কেলার বা 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 অন্যথায়,
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 যেখানে
d = n - m ,
diag_index = k[1] - d , এবং
index_in_diag = n - max(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].
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]`.
