I’ve surface damage depth (D) for 3D points (x, y, z). I’d like remove top and bottom 5% of the D values with their corresponding (x, y, z) from the matrix so that I can plot the remaining 90% of the points. Based on the attached sub set of the data, please kindly assist on the based way to achieve this with the rmoutliers function?

Yes, the rmoutliers function will do the trick. After removing the top and bottom 5% of the values, the vectors below are reduced from 100 elements each to 90 elements each.
% test data
x = rand(1,100);
y = rand(1,100);
z = rand(1,100);
D = rand(1,100);
[D, TF] = rmoutliers(D, 'percentiles', [5 95]);
x(TF) = ;
y(TF) = ;
z(TF) = ;
