                                            double[] y)
                                     throws DimensionMismatchException,
                                            NumberIsTooSmallException,
                                            NonMonotonicSequenceException
```
    Computes a linear interpolating function for the data set.
    
    Specified by:
    
    interpolate in interface UnivariateInterpolator
    
    Parameters:
    
    x - the arguments for the interpolation points
    
    y - the values for the interpolation points
    
    Returns:
    
    a function which interpolates the data set
    
    Throws:
    
    DimensionMismatchException - if x and y have different sizes.
    
    NonMonotonicSequenceException - if x is not sorted in strict increasing order.
    
    NumberIsTooSmallException - if the size of x is smaller than 2.
