uneven

Display unevenly distributed data in 2-D and 3-D as ordinary colour-coded, regularly spaced data.

FFGRID and DENSITY display unevenly distributed data in 2-D and 3-D as ordinary colour-coded, regularly spaced data. This is very useful when dealing with data which are difficult to view using plot3 (which, in my experience, is the case with all 3-D data that are not completely smooth).

FFGRID is a Fast `n' Furious way to do the same job that griddata does for you. The difference is that there is no interpolation. Empty points are left empty rather than trying to fill them using neighbouring points. Also, FFGRID has no problem with multiple points that fall in the same grid cell. Data are displayed using PCOLOR unless output arguments are specified, in which case the matrix of (regularly spaced) data is given along with the vectors s specifying x- and y-dimensions.

DENSITY is akin to HIST in that it displays a density distribution, but this time in 2-D rather than 1-D.

BIN is a small M-file that is needed for FFGRID and DENSITY to do the job right.
