**test_interp_2d_test**,
a MATLAB program which
calls test_interp_2d() to defines= test problems for interpolation of data z(x,y)
depending on a 2D argument.

test_interp_2d, a MATLAB library which defines test problems for interpolation of regular or scattered data z(x,y), depending on a 2D argument.

- test_interp_2d_test.m, calls all the tests.
- test_interp_2d_test.sh, runs all the tests.
- test_interp_2d_test.txt, the output file.

- test_interp_2d_test01.m, simply prints the title of each grid and function.
- test_interp_2d_test02.m, samples each function using each grid.
- test_interp_2d_test03.m, plots the grid points.

**test_interp_2d_test03** makes plots of each grid:

- grid_01.png, Franke's 100 node set.
- grid_02.png, Franke's 33 node set.
- grid_03.png, Lawson's 25 node set.
- grid_04.png, Random 100 node set.
- grid_05.png, Gridded 81 node set.
