sw_mirror#

Syntax#

[~, M] = sw_mirror(n)

[Vp, M] = sw_mirror(n,V)

Description#

[~, M] = sw_mirror(n) generates the transformation matrix corresponding to a mirror plane perpendicular to n.

[Vp, M] = sw_mirror(n,V) mirrors the vectors in V.

To mirror any column vector use the following:

Vp = M * V

To apply mirror plane operation on tensors (\(3\times 3\) matrices) use the following command:

Ap = M * A * M'

Input Arguments#

n: 3D Row vector, normal to the mirror plane.
V: Matrix of 3D vectors, dimensions are \([3\times N]\).

Output Arguments#

Vp: Mirrored vectors in a matrix with dimensions of \([3\times N]\).
mirM: Matrix of the mirror transformation, dimensions are \([3\times 3]\).
