x=[1 2 3 4];
y=[1 2 3 1];
x1=[3 4 5 6 7 8];
y1=[2 6 4 2 5 3];
[x, y, x1, y1] = Tout_Ajuster(x, y, x1, y1)
I want to put zeros where there is no match in x axes to get the same length for (x and x1) so I write a small code (Tout_Ajuster.m) in the output, x1 misses (5 and 6) so y1 miss(4 and 2) What is missing in my function < Tout_Ajuster.m > ???

It would help if you gave us the expected outputs for x1 and y1. Otherwise it's not clear what you're trying to do.

Your question seems ambiguous to me, but based off my interpretation, see if this code gives you the result you're looking for:
% This assumes that none of the matching x values are 0
N = max(numel(x),numel(x1));
xout = zeros(1,N);
yout = zeros(1,N);
x1out = zeros(1,N);
y1out = zeros(1,N);
% Reinsert the known values of x and y
xout(1:numel(x)) = x;
yout(1:numel(y)) = y;
% Values in x1 (and the correponding y1 positions) that do not appear in x are set to zero
for i = 1:numel(x)
matching = find(x(i) == x1);
if isempty(matching) == 1
continue
else
x1out(matching) = x1(matching);
y1out(matching) = y1(matching);
end
end
Gives the following results:
xout =
1 2 3 4 0 0
yout =
1 2 3 1 0 0
x1out =
3 4 0 0 0 0
y1out =
2 6 0 0 0 0

n=max(numel(x),numel(x1))
x=[x zeros(1,n)]
x1=[x1 zeros(1,n)]
y=[y zeros(1,n)]
y1=[y1 zeros(1,n)]
