sorting the values of a vector into a new one by its elements size

Hey all

I made some measurements. Between these values, I interpolated. Now, I want to merge both vectors into one but withouth changing the order. Just copy in the new interpolated values into the intervalls of the measured values.

Is there a predefined function from matlab or do I have to write it myself?

Thanks in advance

upload a short example to know what you are talking about

Alright, sorry:

Say I have a vector

x=[1,5,7,9]

Now, I interpolated between these values and I get a new vector with

y=[0.5,1.5,2,2.5,3,3.5,4...]

and some more values which I left away for now. I don't know wether this is real linear interpolation. I should think about it but it did not matter atm.

Well, now I want to merge both vectors like this:

xnew=[0.5,1,1.5,2,2.5,3,3.5,4...,5,7,9]

Values shall get sorted into the vector by it's values basically.

I hope you understand my problem now. I fear that it is very simple but I don't see it yet.

Try this,

xnew = sort(horzcat(y,x)) % concatane vectors then sort all

%% OR

xnew = horzcat(sort(y),sort(x)) % sort x, sort y seperately then concatanate

The second option is not going to produce the required result. The first one will.

Note that horzcat is the same as [,]

Yes :) thanks!

Thanks for this answer. And please apologize my late response.

Simple and easy solution:

xnew=sort([x y])
