Adding vectors in Matlab

Hi! I have 4 different vectors and I need to add them like this:

mod1+lan1= x1

mod2+lan2= x2

But as you can see in the code the numbers are different.

mod1= [413 443 467 487  531 547 648 666 677 747 859 867 905 936 1388 1631 2121]; 
mod2= [mout8_c mout9_c mout3_c mout10_c mout11_c mout12_c mout1_c mout13_c mout14_c mout15_c mout2_c mout16_c mout17_c mout18_c mout26_c mout6_c mout7_c] 

lan1= [485 560 660 815 1650 2215]; 
lan2=[out1_c out2_c out3_c out4_c out5_c out7_c]

So, what I've done for the x1 is:

x=[mod1 lan1]; 
x1= sort(x); 

 But the problem is on y because I need that the positions would be the same (like for example, on the position 413=mout8_c) but the numbers are totally diferents.

To sum up (maybe it's better if you look at this graph). I have that points and I need to add them in the order of each one.

Thanks a lot in advance and greetings,

Emma

not clear, plus the frog?

Hi Azzi, sorry. The graph is because I think it's more clear. I have 4 vectors: 2x and 2y. But the order of the x are different:

mod1= [413 443 467 487  531 547 648 666 677 747 859 867 905 936 1388 1631 2121]; 
lan1= [485 560 660 815 1650 2215];

The problem is on y. I have different numbers, as you can see in the graph. And I need to add both. What happen? I don't need an order (like 1 2 3 4). I want them like in the image, in that order. But the x are different...

You don't need to sort them to do the regression. If the ‘mout’ values are scalars (as I assume), you can sort both vectors by the values in the x1 vector with the sort function.

If I understand you correctly, this would likely do what you want:

[x1s x1s_idx] = sort(x1);

and the corresponding x2 becomes:

x2s = x2(x1s_idx);

Thanks Star. At the end, I used the below code!

mod1= [413 443 467 487  531 547 648 666 677 747 859 867 905 936 1388 1631 2121]';
lan1= [485 560 660 815 1650 2215]';
mod2 = { 'mout8_c'    'mout9_c'    'mout3_c'    'mout10_c'    'mout11_c'    'mout12_c' 'mout1_c'    'mout13_c'    'mout14_c'    'mout15_c' 'mout2_c'    'mout16_c'    'mout17_c'    'mout18_c'    'mout26_c'    'mout6_c'    'mout7_c'}';
lan2 = {'out1_c'    'out2_c'    'out3_c'    'out4_c'    'out5_c'    'out7_c'}';
[x1,i1] = sort([mod1;lan1]);
y = [mod2;lan2];
out = y(i1);

Thank you a lot Andrei! It works! :)
