theta = compang (varargin)
COMPANG Compute the (2-D or 3-D) angle created by a joint.
A function that takes 3-D data and computes the angle defined
by either three markers (points), or two lines/planes. In the case
of three markers, it computes the angle between two lines
which are constructed by joining the points given by
the three markers. To compute a 2-D angle, the plane
in which to compute the angle is given by the final argument.
THETA = COMPANG (MARKER1, MARKER2, MARKER3) computes the
3-D angle between a line drawn from each point in MARKER1 and
MARKER2 and a line from MARKER2 to MARKER3. The angle
is returned in the vector THETA.
THETA = COMPANG (MARKER1, MARKER2, MARKER3, VIEW) computes the
2-D angle between a line drawn from each point in MARKER1 and
MARKER2 and a line from MARKER2 to MARKER3 from the perspective
given by VIEW.
THETA = COMPANG (LINE1, LINE2, VIEW) works analogously.
VIEW can be either 'xy' (x-y plane, top view in VScope parlance),
'yz' (y-z plane, side view for VScope parlance), or 'xz' (x-z plane,
front view for VScope).
