How to fit the grid to a mesh with voids?

Hello everybody,

I have a mesh that includes some voids in. I would like to create a grid to represent that mesh but when I use mesh grid with X and Y coordinates given; the grid created goes through the voids as well :( Any ideas how to create a grid that fits to my mesh and leave blank the voids I have in the original mesh??

When working with “meshgrid” or “griddata”, it is required that it is a full grid. Any voids would have to be replaced by a NaN.

You could use “scatteredInterpolant” class for your question and replace the voids with a value, example, NaN. The interpolation method depends on the problem you are trying to solve and you can set properties of the class object to achieve this.

Documentation for scatteredInterpolant: http://www.mathworks.com/help/matlab/ref/scatteredinterpolant-class.html

You can look at the Replacement of Sample Values in the examples section of the documentation for help on replacing values.
