retroDeform3d

symmetrize a bilateral landmark configuration

symmetrize a bilateral landmark configuration by removing bending and stretching

retroDeform3d(mat, pairedLM, hmult = 5, alpha = 0.01)

`mat`	matrix with bilateral landmarks
`pairedLM`	2-column integer matrix with the 1st columns containing row indices of left side landmarks and 2nd column the right hand landmarks
`hmult`	factor controlling the bandwidth for calculating local weights (which will be `hmult` * average distance between landmarks and their closest neighbour).
`alpha`	factor controlling spacing along x-axis

`deformed`	matrix containing deformed landmarks
`orig`	matrix containing original landmarks
