Matrix.flipOrientation

raytracing.Matrix.flipOrientation(self)

We flip the element around (as in, we turn a lens around front-back). This is useful for real elements and for groups.

Returns:: Matrix – An element with the properties of the flipped original element
Return type:: object of Matrix class

Examples

>>> # Mat is an ABCD matrix of an object
>>> Mat= Matrix(A=1,B=0,C=-1/5,D=1,physicalLength=2,frontVertex=-1,backVertex=2,label='Lens')
>>> _ = Mat.display()
>>> flippedMat=Mat.flipOrientation()
>>> _ = flippedMat.display()
