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

Source Code:

• 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.
