returns a scaling matrix with scaling factors sx, sy, and sz
in X, Y, and Z direction, respectively. Do not keep a reference to
the scaling matrix unless you set the copy flag.
returns a translation matrix with translation offsets tx, ty,
and tz in X, Y, and Z direction, respectively. Do not keep a
reference to the translation matrix unless you set the copy flag.
transforms data to frame coordinates. In the simplest case, returns
the dot product of the data point matrix dataA and the transformation
matrix transA. If funcT is not None, it provides 2-tuples
describing a transformation for the x, y, or z axis, respectively
(a transformation function for the corresponding axis and its arguments).
