select_morphp: Select morphing points
In kmarchlewski/morphfoil: Morphing of an airfoil mesh for xred solver

Description Usage Arguments Value Examples

The function selects the morphing points (which control a mesh morphing) from airfoil points. Each morphing point is selected such that it is neares to a corresponding point from xcoord vector.

1	select_morphp(airfoil, surf, xcoord)

`airfoil`	A data frame containing coordinates of airfoil points.
`surf`	A character string indicating upper or lower curve of the airfoil.
`xcoord`	A vector of x-coordinates of the requested points.

A list of two elements: a logical vector ($sel) indicating which points are selected and a data frame ($coord) containing coordinates of the selected points.
