Good morning,
I have a problem concerning the data of a matrix. Each data represents the value of curvature of a plate through its surface. However, in some regions of the surface (and then, in some group of values of the matrix) there are some strange values that I need to be smoothed. I can't filter out those values because I need all the values of the matrix, so it's just necessary to smooth those strange values. I tried to use the function "smoothdata", but the problem is that it smooths all the data of the matrix, while I need the correct values to remain not modified. I need some local smoothing/filtering.
You can find attached an image which show the plot of these curvature values through the surface.
Here is the code of this plot, KxxFE is the matrix of interest.
figure('color',[1 1 1])
surf(KxxFE);
colorbar;
colormap('hot');
Any help about this? Thank you so much
