Problem 2009. Insert certain elements into a vector.
We start with vector V. Some values W will be inserted into V, at positions U.
Say, V contains [1 2 3 4 5] and W is [0 -1] while U is [2 4], then the function should return as a result [1 0 2 3 -1 4 5]. In other words, the values at the positions in which a new value is inserted shift to the end of the vector. And the indices indicated in U are the original indices, when no elements have been inserted yet.
Insertion at position one-after-the-last element of v just appends that value to the vector v.
Your task is to find the most efficient or elegant solution to code this in Matlab language.
(Eval and Regexp are not your friends this time.)
