- Method Detail
  - interpolate
```
CalculusFieldBivariateFunction<T> interpolate(T[] xval,
                                              T[] yval,
                                              T[][] fval)
                                       throws MathIllegalArgumentException
```
    Compute an interpolating function for the dataset.
    
    Parameters:
    
    xval - All the x-coordinates of the interpolation points, sorted in increasing order.
    
    yval - All the y-coordinates of the interpolation points, sorted in increasing order.
    
    fval - The values of the interpolation points on all the grid knots: fval[i][j] = f(xval[i], yval[j]).
    
    Returns:
    
    a function which interpolates the dataset.
    
    Throws:
    
    MathIllegalArgumentException - if any of the arrays has zero length.
    
    MathIllegalArgumentException - if the array lengths are inconsistent.
    
    MathIllegalArgumentException - if the array is not sorted.
    
    MathIllegalArgumentException - if the number of points is too small for the order of the interpolation
