scalar_projection Function

public pure function scalar_projection(x, y) result(rst)

Computes the projection of vector x onto vector y. The scalar projection is defined such that $s = \frac{\vec{x} \cdot \vec{y}}{||\vec{y}||}$.

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=real64),	intent(in),		dimension(:)	::	x	The vector to project.
real(kind=real64),	intent(in),		dimension(size(x))	::	y	The vector onto which x should be projected.

Return Value real(kind=real64)

The scalar projection of x onto y.
