A very simple 3-line function that returns the index and the value of the element of vector x that is closest to a particular numerical value.
If more than one element is equally close, returns vectors of indicies and values.
Examples: If x=[1 2 4 3 5 9 6 4 5 3 1], then val2ind(x,6)=7 and val2ind(x,5.1)=[5 9]
[indices values]=val2ind(x,3.3) returns indices = [4 10] and values = [3 3].
Sample use: to determine the index and value of an element of a vector from the x,y values obtained by clicking on a plot of that vector using ginput.
