21 Jul 2009	Spherical Harmonics This function generates the Spherical Harmonics basis functions of degree L and order M. Author: Daniel Ennis	Jacek	Nice work . One minor comment: the output argument Ymn has the elevation and azimuth dimensions flipped with respect to the input RES argument, due to the nature of meshgrid. Thus, the rows of the output Ymn refer to elevation, while the columns of the output Ymn refer to azimuth.

13 Jun 2009	Numerical derivative of analytic function Calculate the numerical derivative of an analytic function with different methods. Author: Daniel Ennis	Salexa, Juliette	I'm looking for a package that approximates derivatives for NUMERICALLY defined functions (not analytic) .. I have two arrays: x=0:0.5:10 , and fun= a vector that defines my function at each of those values of x. Now I want the derivative of fun with respect to x at each value of x. Does such a package exist ??
04 Jun 2009	wireframe This function plots a sub-sampled wireframe of a surface. Author: Daniel Ennis	Lansky, Lukas	Nice. If you want to quickly try it out: x = [0:0.1:10]; y = [0:0.1:10]; z = sin(x)'*cos(y); mesh(x,y,z); wireframe(x,y,z,5);
04 Jun 2009	wireframe This function plots a sub-sampled wireframe of a surface. Author: Daniel Ennis	Crivaro, Marko	Really good, does that it promises. Especially helpful when visualizing huge (accurate) grids.
