tform = trvec2tform(trvec)
converts the Cartesian representation of the translation vector
trvec to the corresponding homogeneous
transformation tform. When using the
transformation matrix, premultiply it by the coordinates to be
transformed (as opposed to postmultiplying).
Cartesian representation of a translation vector,
specified as an n-by-2 matrix if
tform is a
3-by-3-by-n array and an
n-by-3 matrix if
tform is a
4-by-4-by-n array.
n is the number of translation
vectors. Each vector is of the form
[xy] or [xyz].
Homogeneous transformation, returned as a
3-by-3-by-n array or
4-by-4-by-n array.
n is the number of homogeneous
transformations. When using the rotation matrix,
premultiply it with the coordinates to be rotated
(as opposed to postmultiplying).
Example: [0 0 1 0; 0 1 0 0; -1 0 0 0; 0 0 0

2-D homogeneous transformation matrices are of the form:
3-D homogeneous transformation matrices are of the form:
The trvec argument now accepts 2-D translation
vectors as a n-by-2 matrix and
trvec2tform outputs 2-D homogeneous
transformation matrices as a 3-by-3-by-n
array.
