I have a 3D matrix where each element corresponds to the density at point (X,Y,Z), see attached. The coordinates and data are loaded by the below code. The first two axis of xyPhi correspond to xh and yh, and the third axis corresponds to z. I would like to do a 3D density plot using this data, it should look something like a puck. I essentially want the equivalent of ListDensityPlot3D in Mathematica. Here is what the plot looks like in mathematica

M=60;%number of radial spatial lattice points
N = 60; %number of z-axis lattice points
R = 15;
Z = 14;
dr=double(2*R/(2*M+1));
dz = 2*Z/N;
xh = dr*(-M:1:M);
yh = dr*(-M:1:M);
z = -Z*ones(N+1,1) + dz*(0:1:N).';
