Hi, I've a meshgrid

[X,Y,Z] = meshgrid(0:250:1000,0:250:1000,0:250:1000)

and I computed in each node a value of temperature. I've a 5x5x5 matrix named T_geotherm:

val(:,:,1) =
0000   18.0000   18.0000   18.0000   18.0000
0000   18.0000   18.0000   18.0000   18.0000
0000   18.0000   18.5000   18.5000   18.5000
0000   18.0000   18.5000   18.5000   19.0000
0000   19.0000   20.0000   20.0000   20.0000

val(:,:,2) =

2356   33.2356   34.0689   34.0689   34.6245
2356   33.2356   34.0689   34.6245   34.6245
2356   34.0689   34.5689   35.1245   35.1245
2356   34.0689   35.1245   35.1245   35.6245
2356   35.0689   36.6245   37.1800   37.1800

val(:,:,3) =

3670   48.3670   50.0337   50.0337   51.1448
3670   48.3670   50.0337   51.1448   51.1448
3670   50.0337   50.5337   51.6448   51.6448
3670   50.0337   51.6448   51.6448   52.1448
3670   51.0337   53.1448   54.2559   54.2559

val(:,:,4) =

3943   63.3943   65.8943   65.8943   67.5609
3943   63.3943   65.8943   67.5609   67.5609
3943   65.8943   66.3943   68.0609   68.0609
3943   65.8943   68.0609   68.0609   68.5609
3943   66.8943   69.5609   71.2276   71.2276

val(:,:,5) =

7427   68.7427   71.5427   71.5427   73.4094
7427   68.7427   71.5427   73.4094   73.4094
7427   71.5427   72.0427   73.9094   73.9094
7427   71.5427   73.9094   73.9094   74.4094
7427   72.5427   75.4094   77.2760   77.2760

How can I display the results on a plot? For example several slices at different depths or display an isosurface of 60°C?

Thanks for the help

Please post, what you have tried so far and which problems occurred. Is there any chance that we can identify what "60°C" has to do with your data?

Hi Jan, My data are underground temperatures computed at selected depth. I solved the problem regarding how to display the trend of a selected temperature (i.e. 60°C) through an isosurface in this manner:

p = patch(isosurface(X,Y,Z,T_geotherm,60));
isonormals(X,Y,Z,T_geotherm,p);
set(p,'FaceColor','b','EdgeColor','k','FaceAlpha',0.1,'EdgeColor','none');
