In qfratio: Moments and Distributions of Ratios of Quadratic Forms Using Recursion
sum_counterdiag R Documentation
Summing up counter-diagonal elements
Description
sum_counterdiag() sums up counter-diagonal elements of
a square matrix from the upper-left; i.e.,
c(X[1, 1], X[1, 2] + X[2, 1], X[1, 3] + X[2, 2] + X[3, 1], ...)
(or a sequence of \sum_{i=1}^k x_{i, k - i + 1} for
k = 1, 2, ...). sum_counterdiag3D() does a comparable in
a 3D cubic array. No check is done on the structure of X.
Usage
sum_counterdiag(X)
sum_counterdiag3D(X)
Arguments
X
Square matrix or cubic array
