SE2 Representation of 2D rigid-body motion

This subclasss of RTBPose is an object that represents rigid-body motion in 2D.

Internally this is a 3x3 homogeneous transformation matrix (3x3) belonging to

the group SE(2).

Constructor methods::

SE2 general constructor

SE2.exp exponentiate an se(2) matrix

SE2.rand random transformation

new new SE2 object

Display and print methods::

animate ^graphically animate coordinate frame for pose

display ^print the pose in human readable matrix form

plot ^graphically display coordinate frame for pose

print ^print the pose in single line format

Group operations::

* ^mtimes: multiplication (group operator, transform point)

/ ^mrdivide: multiply by inverse

^ ^mpower: exponentiate (integer only):

inv inverse

prod ^product of elements

Methods::

det determinant of matrix component

eig eigenvalues of matrix component

log logarithm of rotation matrix

inv inverse

simplify* apply symbolic simplication to all elements

interp interpolate between poses

theta rotation angle

Information and test methods::

dim ^returns 2

isSE ^returns true

issym ^test if rotation matrix has symbolic elements

SE2.isa test if matrix is SE(2)

Conversion methods::

char* convert to human readable matrix as a string

SE2.convert convert SE2 object or SE(2) matrix to SE2 object

double convert to rotation matrix

R convert to rotation matrix

SE3 convert to SE3 object with zero translation

SO2 convert rotational part to SO2 object

T convert to homogeneous transformation matrix

Twist convert to Twist object

t get.t: convert to translation column vector

Compatibility methods::

isrot2 ^returns false

ishomog2 ^returns true

tr2rt ^convert to rotation matrix and translation vector

t2r ^convert to rotation matrix

transl2 ^translation as a row vector

trprint2 ^print single line representation

trplot2 ^plot coordinate frame

tranimate2 ^animate coordinate frame

^ inherited from RTBPose class.
