MATLAB: How to perform median filtering on a 3D set of data, the same way that MEDFILT2 works on 2D sets in Image Processing Toolbox

I would like to perform median filtering on a 3D set of data, in the same way that MEDFILT2 works on 2D sets.

The ability to perform 3D median filtering on data is not automatically available in the Image Processing Toolbox.

The following submission on MATLAB Central includes a function that performs 3D median filtering.

Your Az vector is mainly concentrated around 169, therefore normal median filtering destroys the sudden peaks. Using Padding option as 'symmetric' might help. Refer the code below.

load cond2a.dat   
Ax = cond2a(:, 1);    
Ay = cond2a(:, 2);    
Az = cond2a(:, 3);    
Znew = medfilt2(Az, 'symmetric'); 
figure;  plot(Az);
hold on;
plot(Znew);
legend({'Original Data', 'Median filtered data'});
