Detailed Description

error ellipse, "ellipse walls" version

///    ERROR_ELLIPSE(C22) - Given a 2x2 covariance matrix, plot the
///    associated error ellipse, at the origin. It returns a graphics handle
///    of the ellipse that was drawn.
///
///    ERROR_ELLIPSE(C33) - Given a 3x3 covariance matrix, plot the
///    associated error ellipsoid, at the origin, as well as its projections
///    onto the three axes. Returns a vector of 4 graphics handles, for the
///    three ellipses (in the X-Y, Y-Z, and Z-X planes, respectively) and for
///    the ellipsoid.
///
///    ERROR_ELLIPSE(C,MU) - Plot the ellipse, or ellipsoid, centered at MU,
///    a vector whose length should match that of C (which is 2x2 or 3x3).
///
///    ERROR_ELLIPSE(...,'Property1',Value1,'Name2',Value2,...) sets the
///    values of specified properties, including:
///      'C' - Alternate method of specifying the covariance matrix
///      'mu' - Alternate method of specifying the ellipse (-oid) center
///      'conf' - A value betwen 0 and 1 specifying the confidence interval.
///        the default is 0.5 which is the 50%> error ellipse.
///      'scale' - Allow the plot the be scaled to difference units.
///      'style' - A plotting style used to format ellipses.
///      'clip' - specifies a clipping ruleRadii. Portions of the ellipse, -oid,
///        outside the ruleRadii will not be shown.
///
///    NOTES: C must be positive definite for this function to work properly.
