rotation.matrix.between.vectors: This function returns n by n rotation matrix that align...

In browarsoftware/RMoCap: Package for processing and kinematic analyzing motion capture data.

Description

Both vector x and y has to be normalized.

Usage

rotation.matrix.between.vectors(x, y)

Arguments

x	vector to be rotated (has to be normalized).
y	reference vector (has to be normalized).

Value

n x n rotation matrix.

Examples

x <- vector.to.unit(c(1,0,0))
y <- vector.to.unit(c(0,1,0))
Rx2y <- rotation.matrix.between.vectors(x, y)
x %*% Rx2y
y
x <- vector.to.unit(c(5,0,2,4,6))
y <- vector.to.unit(c(0,1,0,8,-5))
Rx2y <- rotation.matrix.between.vectors(x, y)
x %*% Rx2y
y
x <- vector.to.unit(c(8,0,0))
y <- vector.to.unit(c(2,0,0))
Rx2y <- rotation.matrix.between.vectors(x, y)
x %*% Rx2y
y
