UprodR {gogarch}R Documentation

Creation of an orthogonal matrix

Description

This function returns an orthogonal matrix which results of the matrix products of rotation matrices.

Usage

UprodR(theta)

Arguments

theta

Vector, of angles of the rotation matrices.

Details

The length of theta must be equal to m * (m - 1) / 2, where m is the dimension of the orthogonal matrix. The elements of theta must lie in the interval [0, \pi/2).

Value

result

Object of class Orthom.
