We propose a method to search the inverse matrix for a type of special multiplied triangular matrix quickly. The proposed method can be used for the decomposition of Diagonal matrix, Lower triangular ...

The lower triangular part of `tril` defines this operator. The strictly upper triangle is ignored. is_non_singular: Expect that this operator is non-singular. This operator is non-singular if and only ...

In the present paper, an attempt is made to obtain the degree of approximation of conjugate of functions (signals) belonging to the generalized weighted W (LP, ξ (t)), (p ≥ 1)-class, by using lower ...

Discover the degree of approximation for generalized weighted functions using lower triangular matrix operator of Fourier series. Explore the conjugate series in this groundbreaking paper.

An Upper Triangular matrix is one which is calculated by replacing the non zero elements by zero, which are leftward of the diagonal. Similar for Lower Triangular matrix. Create a console application ...
