pwl_interp_2d, a Python code which evaluates a piecewise linear interpolant of data depending on a 2D argument, defined on on a product grid, so that p(x(i),y(j)) = z(i,j).

pwl_interp_2d is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.
padua, a python code which returns the points and weights for padu sets, useful for interpolation in 2d. matlab graphics are used to plot the points.
pwl_interp_1d, a python code which interpolates a set of data using a piecewise linear function.
r8lib, a python code which contains many utility routines using double precision real (r8) arithmetic.
rbf_interp_2d, a python code which defines and evaluates radial basis function (rbf) interpolants to 2d data.
test_interp_2d, a python code which defines test problems for interpolation of data z(x,y), depending on a 2d argument.
