Given a desired value "y0", this function finds all the elements "y" in a vector whose values are the closest to "y0" in the whole vector, and also the positions "xi". So, the output is a set of points [xi,y0] given in two vectors, one for the values and another one for the positions.
The inputs are:
-Vector.
-Value that you want to find in the vector "y0".

The outputs are:
-The closest values to "y0" in the function (by means the real "y" values).
-The position "xi" of those "y" values.

I hope it is useful for all of you. If you have any suggestion, please, tell me.

Yields the closest value in case that the wanted value is not in the range of the input vector

Little optimization

The algorithm remains being the same, but I have made some little changes.
- When the function starts, it will ask for the value that you are looking for.
- It draws a plot to help you to understand the values and positions that the function found.
