    Computes an interpolating function for the data set.
    
    Specified by:
    
    interpolate in interface BivariateRealGridInterpolator
    
    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 data set.
    
    Throws:
    
    MathException - if arguments violate assumptions made by the interpolation algorithm.
    
    java.lang.IllegalArgumentException
