## This private function is to be common to all functions that have an option
## for the interpolation method to use. For matlab compatibility, bicubic and
## bilinear are accepted which are the same as cubic and linear. This does not
## actually check if the method is valid, we leave that to interp2. The reason
## is that if interp2 implements a new method, all this functions will
## automatically work with it.
function method = interp_method (method)
method = tolower (method);
switch method
case "bicubic", method = "cubic";
case "bilinear", method = "linear";
case "triangle", method = "linear"; # interpolation kernel
endswitch
endfunction
