My Code is missing two values and I need help:
function y = lagrange (X, Y, x)
n = length(X);
if n ~= length (Y)
error ('X and Y must have the same length.');
end
y = zeros(size(x));
for i = 1:n
L = ones(size(x));
for j = [1:i-1 i+1:n]
L = %complete missing line
end
y = %complete missing line
end
end
