MATLAB: Plotting 4D with 3 vectors and 1 matrix

4d plot4d plottingplotting

Hello,

I am solving a problem where I have three vectors (one for each 3D dimension), with different lengths and unevenly spaced, and a temperature matrix where each entry corresponds to the temperature at the position (x(i),y(j),z(k)). My goal is to make a 4D plot where the forth dimension (temperature) is represented my a colour (see attached file).

I have searched for an answer but did not get any solution for the conditions that I presented (3 vectors with 1 matrix). What function or approach would you recommend me to try?

*Data type*
length of x = M
length of y = N
length of z = P
size of Temperature matrix = M x N x P

Thanks in advance.

You can create a scattered interpolant and then sample it along grids. But as is hinted in your image, the outside is going to hide the inside when you plot. You can work with a voxel viewing routine or you can create isosurfaces to try to deal with that.

My recommendation would be to set the interpolated data to nan in those regions before doing the contour plot.

However, since you have scattered data, you have the challenge of determining which points are "near enough" to explicit scattered data that they should validly be interpolated, and which points are instead to be interpreted as being too far from the scattered data and so should be interpreted as being outside the map.

You could consider a pdist2() approach but it appears you have a fair bit of data, so that would not be computationally feasible. You might be able to take advantage of kd-tree approaches; https://www.mathworks.com/help/stats/classification-using-nearest-neighbors.html

z = p.vertices(:,3) ;
tri = p.faces ;
trisurf(tri,x,y,z) ;
