Abstract: In this paper we propose a new representation for FFT algorithms called the triangular matrix representation. This representation is more general than the binary tree representation and, ...

Abstract: 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 ...

This program samples an input matrix of binary values, building a square matrix from a random sample of row and column indices. The resulting square matrix is tested to determine if it is an upper- or ...

The most probable cause is e.g. this line of code, which makes the function accept only general matrices, triangular matrices fail with the error. This is present in ...
