Get the transformation matrix from the Morpho::mirror function

make.mirror.transform(x, icpiter = 50, subsample = NULL,
  pcAlign = FALSE, mirroraxis = 1, initPC = TRUE,
  initCenter = TRUE, mc.cores = 2)

Arguments

x	k x 3 matrix or mesh3d
icpiter	Number of iterations to run
subsample	integer: use only a subset for icp matching
pcAlign	if TRUE, the icp will be preceded by an alignment of the principal axis (only used if icpiter > 0), currently only works for 3D data
mirroraxis	integer: which axis to mirror at
initPC	logical: if TRUE the data will be prealigned by its principal axes
initCenter	logical: if TRUE and initPC=FALSE, x will be translated to its centroid before mirroring
mc.cores	use parallel processing to find best alignment to original shape
...	additional arguments passed to methods
