I'm trying to make a surface approximation to describe the required input torque to drive a hydraulic motor operating under certain load conditions. My inputs are: output flow, output pressure and input shaft speed. I have scattered measurement data where the relationship between these variables are to be found. I read in some of the earlier posts that gridfit could be extended to higher-dimension fits. Do you have any version where a 3rd dimension can be included that I could try?
After running 3D mesh plot of displacement, and deleting markers I then use the 'save validx and valid y' button in the menu. I can save the .dat files, however I get the same error every time I try to open them:
Undefined function 'sum' for input arguments of type 'cell'.
Error in mean (line 30)
y = sum(x,dim)/size(x,dim);
Error in displacement (line 52)
I don't get this error with the original validx and y files. But then I need to re-delete badly tracked markers. Has anyone encountered this?
Thanks for the code
hello, thanks for the code.,
it would be of great help,if you could send the edited copy of the same 'to save the values of displacement vs position'
to following address : firstname.lastname@example.org
hello, really appreciate for your work. I'm a student in Sheffield University.
i'm using your code for deformation measurement. I met some difficulties of extracting numerical data from the DIC result figure. could you help out? really thanks.
Gridfit is very nice. I have written an update that adds bicubic interpolation and improves the internal scaling (makes surface smoothness completely independent of the x/y grid size). If I send you the code, would you update Gridfit?
