Is a upper triangular matrix normal?
Repeating this for all rows, we see that A is a diagonal matrix. Thus any normal upper triangular matrix is a diagonal matrix.
What is lower triangular matrix in C?
Lower triangular matrix is a matrix which has elements below the principle diagonal including the principle diagonal elements and rest elements as zero.
What is upper triangle and lower triangle?
In the mathematical discipline of linear algebra, a triangular matrix is a special kind of square matrix. A square matrix is called lower triangular if all the entries above the main diagonal are zero. Similarly, a square matrix is called upper triangular if all the entries below the main diagonal are zero.
What are sparse upper triangular and lower matrix?
Lower triangular matrix is a matrix which contains elements below principle diagonal including principle diagonal elements and rest of the elements are 0. Upper triangular matrix is a matrix which contains elements above principle diagonal including principle diagonal elements and rest of the elements are 0.

What is TRIU?
Description. triu(A) returns a triangular matrix that retains the upper part of the matrix A . The lower triangle of the resulting matrix is padded with zeros. triu( A , k ) returns a matrix that retains the elements of A on and above the k -th diagonal.
What is upper triangular matrix in C?
An Upper triangle Matrix in C is a square matrix where elements below the main diagonal are zeros.
What is upper and lower diagonal matrix?
A square matrix whose all elements above the main diagonal are zero is called a lower triangular matrix. A square matrix whose all elements below the main diagonal are zero is called an upper triangular matrix.

What is Torch TRIU?
torch. triu (input, diagonal=0, *, out=None) → Tensor. Returns the upper triangular part of a matrix (2-D tensor) or batch of matrices input , the other elements of the result tensor out are set to 0. The upper triangular part of the matrix is defined as the elements on and above the diagonal.
What is a lower matrix?
A lower-triangular matrix is a matrix which only has nonzero entries on the downwards-diagonal and below it.
