Find indices of values in vec that are closest to requested values
vals.
Parameters:
vec:numpy array
Vector of values.
vals: list of values | value
Values to find closest representatives of in the vec vector.
Returns:
idx:numpy array of int | int
Indices of vec values closest to vals. If one value was passed in
vals then idx will also be one value. If two or more values were
passed in vals the output is a numpy array of indices.
