- Method Detail
  - interpolate
```
MultivariateRealFunction interpolate(double[][] xval,
                                     double[] yval)
                              throws MathException,
                                     java.lang.IllegalArgumentException
```
    Computes an interpolating function for the data set.
    
    Parameters:
    
    xval - the arguments for the interpolation points. xval[i][0] is the first component of interpolation point i, xval[i][1] is the second component, and so on until xval[i][d-1], the last component of that interpolation point (where d is thus the dimension of the space).
    
    yval - the values for the interpolation points
    
    Returns:
    
    a function which interpolates the data set
    
    Throws:
    
    MathException - if arguments violate assumptions made by the interpolation algorithm or some dimension mismatch occurs
    
    java.lang.IllegalArgumentException - if there are no data (xval null or zero length)
