12 Mar 2014 SHADOWPLOT Add a shadow to an existing surface plot. Author: Michelle Hirsch

I repeat Usman's request. Is there any way to add projections of lines/points too? (e.g., using plot3/line/quiver)

25 Jul 2013 Split Bregman method for Total Variation Denoising Implement the split Bregman method for total variation denoising Author: Benjamin Tremoulheac

niu, can you just zero-pad your image?

10 Jul 2013 Field Mapping Toolbox Methods for B0 Mapping with Multi-Channel RF Coils in MRI (Robinson and Jovicich, MRM, 2011) Author: Simon Robinson

medfil3 works as perfect extension to the MATLAB 1D and 2D versions.
Very fast implementation.
Good documentation (consistent with built-ins).

Very appreciative.

I don't think your multiplication of the frequency response is correct for 3D Gabor. To extend to 3D it should be:

exp(j2pi(Fsin(theta)cos(phi)x'+Fsin(theta)sin(phi)y'+Fcos(theta)z')]

http://www.sciencedirect.com/science/article/pii/S0262885605000934
Where F is the amplitude of the wave with frequency (x0,y0,z0).
