16 Jan 2014 Spherical Harmonics This function generates the Spherical Harmonics basis functions of degree L and order M. Author: Daniel Ennis Giorgos

Nice function.
An interesting improvement would be to use the Schmidt semi-normalised Legendre functions as to avoid the use of factorials, which would make the output much more accurate for high L values.

03 Oct 2013 Bullseye Polar Data Plot This function creates smooth patches of polar data in "bullseye" plot. Author: Daniel Ennis Sharmin

Is there a way to make multiple bullseye plots as sublots?

03 Jul 2012 Plot 3D Color Line Plots a 3D line with color encoding along the length using the patch function. Author: Daniel Ennis Diamond, Andrew

Apparently, when consecutive x,y points are the same dl will be [0,0,1] and so you end up with alpha and cross(Nz,dl) being 0 yielding a rotation matrix R that is just NaNs and nothing will be plotted for that segment.

There may be more elegant fixes but checking for that and using R=eye(3) if it is nan seems to solve this.

if(isnan(R(1)))
R=eye(3);
end

13 Jun 2012 Spherical Harmonics This function generates the Spherical Harmonics basis functions of degree L and order M. Author: Daniel Ennis seda

Are there any function or example to generate cylindrical harmonics or normal modes of a cylinder??

06 Mar 2012 Plot 3D Color Line Plots a 3D line with color encoding along the length using the patch function. Author: Daniel Ennis Arlow, Richard

This works great! Is there any way to change the color mapping in terms of intensity and/or using other colormaps?
