interp3
in [Matlab]

From: Adam on 25 Nov 2009 13:50 Hi, This is probably a basic question, but I haven't worked that much with matlab yet. I am outputting data in 3d mesh using matlab using 3 independent parameters. I have a problem with interpolating the data as I can't get the commando interp3 to work. If someone could show me a concrete example of using interp3 or a good text on the subject I would be very thankful.

Rather use GRIDDATA3 or TriScatteredInterp for scattered data. INTERP3 is used for tensorial gridded data only. Bruno

From: Adam on 27 Nov 2009 11:23 I am a bit stuck as I am not sure how to use the griddata3, my experience is limited using matlab. I've used matlab to create 3d graphs using a vector with 5 fixed values as X, a vector with 7 fixed values as Y. As Z I have 5*7 measured values. I need to interpolate my graph to "smoothen" the lines in the graph, probably using griddata3 as mentioned. Could someone show me a practical example of needed matlab code for this I would be very thankful.
