Conditions in If sats true one each bUT NOT SIMULTANEOUSLY
Hi, I have an if sats with three statements. All statements are true one each but not simultaneously. Here is the If statement with the three conditions: if isnan(coups(ii,dd)) && isempty(mats(ii,dd))==0 && isnan(mats(ii,dd))==0; I have tested both & and && but note of them is working. Any ideas? ... 16 Dec 2009 17:57

Interpolation in an unstructured field
I have unstructured [x y z] data from CFD calculations, and would like to convert them to a rectangular meshed grid. - is that possible? I'm thinking of something like N = 50; M = 5; x = rand(1,N); y = rand(1,N); z = rand(1,N); [Xi Yi] = meshgrid(linspace(0,1,M)); Zi = interpUNSTRUCTURED(x,y,z,Xi,Yi) re... 16 Dec 2009 06:52

Vectorized call to TriScatteredInterp?
I am looking to interpolate a 2d set of data (well, I have X and Y coordinates that have corresponding values V). I have several parameters that depend on the same X and Y, (ie V1 through V4). Problem is, I have several different (X,Y) spaces that may be used (my data depends on a few different (X,Y) calibrations, and ... 16 Dec 2009 03:38
