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

Description Usage Arguments Value Examples

The function selects points from airfoil points which should not be moved during morphing of a mesh.

1	select_constr(airfoil, surf, limits)

`airfoil`	A data frame containing coordinates of airfoil points.
`surf`	A character string indicating upper or lower curve of the airfoil.
`limits`	A matrix which in each row contains limits within wich the constraining points should lie.

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.
