# Transformation of steroids by trichoderma hamatum

To reflect a point through a plane a x + b y + c z = 0 {\displaystyle ax+by+cz=0} (which goes through the origin), one can use A = I − 2 N N T {\displaystyle \mathbf {A} =\mathbf {I} -2\mathbf {NN} ^{T}} , where I {\displaystyle \mathbf {I} } is the 3x3 identity matrix and N {\displaystyle \mathbf {N} } is the three-dimensional unit vector for the vector normal of the plane. If the L2 norm of a , b , {\displaystyle a,b,} and c {\displaystyle c} is unity, the transformation matrix can be expressed as:
