Find values in a vector or function
For a function y=f(x), this script looks for all the "x" values for a desired value of "y" (y0).

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.
