PLOT_GAUSSIAN_ELLIPSOIDS plots 2-d and 3-d Gaussian distributions.
H = PLOT_GAUSSIAN_ELLIPSOIDS(M, C) plots the distribution specified by mean M and covariance C. The distribution is plotted as an ellipse (in 2-d) or an ellipsoid (in 3-d). By default, the distributions are plotted in the current axes. H is the graphics handle to the plotted ellipse or ellipsoid.
PLOT_GAUSSIAN_ELLIPSOIDS(M, C, SD) uses SD as the standard deviation along the major and minor axes (larger SD => larger ellipse). By default, SD = 1.
PLOT_GAUSSIAN_ELLIPSOIDS(M, C, SD, NPTS) plots the ellipse or ellipsoid with a resolution of NPTS (ellipsoids are generated on an NPTS x NPTS mesh). By default, NPTS = 50 for ellipses, and 20 for ellipsoids.
PLOT_GAUSSIAN_ELLIPSOIDS(M, C, SD, NPTS, AX) adds the plot to the axes specified by the axis handle AX.
