Hi,
I have a question about plotting 3D matrices. I have data at specific points, as a 3d matrix, and I have the unevenly spaced X,Y,Z data for each point as 3d matrices, respectively. Basically I need to visualize the data over a volume given the XYZ coordinates of each data point.
I looked up thread575-101753.
Please advise whether mesh grid would help in this case(I think it generates evenly spaced coordinate data).
Any suggestions will be most helpful.

Here is a sample of the data:
C(:,:,1)=[ 0.4185 0.332 0.2365 0.0635;
0.3255 0.258 0.184 0.0495;
0.2325 0.1845 0.1315 0.035;
0.1395 0.1105 0.079 0.021;
