function y=nndef(x,d)
%NNDEF Replace missing and NaN values with defaults.

%	*WARNING*: This function is undocumented as it may be altered
%	at any time in the future without warning.

% NNDEF(X,D)
%   X - Row vector of proposed values.
%   D - Row vector of default values.
% Returns X with all non-finite and missing values with
%   the corresponding values in D.
%
% EXAMPLE: x = [1 2 NaN 4 5];
%          d = [10 20 30 40 50 60];
%          y = nndef(x,d)
