i have high resolution lat, lon, height data (matrix form) but they are not gridded. how would I create 3D plot in matlab as lat on x -axis, lon on y-axis and height on z-axis?

I have to produce an 3D image as shown in below by using above said data of lat,lon and height.

Thanks in advance.

Unfortunately, a glaring weakness in Matlab plotting functions is surface plots directly from scattered data...you'll have to try to interpolate enough to grid it to use any of the builtins (in base product, anyway, there could be something in some toolbox I'm unaware of).

There's example at https://www.mathworks.com/help/matlab/visualize/representing-a-matrix-as-a-surface.html bottom half of page. Good luck.

If you have access, TecPlot is much more powerful in this regard.
