Description
Calculate a number of elements in a lower/upper triangle of a symmetric
matrix of size n*n when n is given.
Usage
1
nDiag2nTri(n)
Arguments
n
A number of diagonal elements in a symmetric matrix.
Details
nCoeff = (n^2-n)/2, thus
n = (1+sqrt(1+8*nCoeff))/2
Value
A number of elements in a lower/upper triangle of a matrix
(excluding the diagonal).
