I have a vector a=[0.2 2 3 4] and I have another vector that is b=[0.1 1 2 5] so how can I insert each element of b between elements of a and the last element of b after the last element of a?

So in effect, take 0.1 from b, insert it between 0.2 and 2 in a, take 1 from b and insert it between 2 and 3 in a, take 2 from b and insert it between 3 and 4 and take 5 from b and insert it after 4

so after this process, a new matrix say c will be c=[0.2 0.1 2 1 3 2 4 5]

The logic I would assume would be used is take the last element of b and remove it, the follow a process to insert the remaining values of b into a then in that new vector, insert the last value at the end. Idk, any help is greatly appreciated, thanks.

在 MATLAB Online 中打开

Is it just

c = [a;b]
c = c(:)

Did I understand it correctly?

Wow it worked!! thanks so much, was trying to figure this out for ages, could you please explain how this works, the logic behind it? Thanks alot!

You are just trying to interleaving the two vectors. When MATLAB converts a matrix to vector using colon, it connects columns together, that's why you can use this trick to interleaving the two.
