Triangle patterns are aptly named because the upper and lower trendlines ultimately meet at the apex on the right side, forming a corner. These patterns are formed once the trading range of a ...

Helper function MatInverseUpperTri() is used to compute the inverse of the R matrix that results from QR decomposition. The technique used to compute the inverse of an upper triangular or lower ...

.cofactor() Returns the cofactor of the matrix. .copy() Returns a copy of the matrix. .cut() Returns a smaller matrix by removing the required row and column. The default of row and column is None.

Abstract: Compared with general linear block code encoding, LDPC encoding with lower triangular check matrix and approximate lower triangular check matrix carry out encoding directly by parity check ...

A descending triangle is a chart pattern used in technical analysis created by drawing one trend line connecting a series of lower highs and a second horizontal trend line connecting a series of lows.

Calculation of L′ is coded in R function getLp (Data Availability Statement), and it requires a pedigree data frame as input. We used R package “Matrix” (Bates and Maechler, 2019) for sparse matrices.
