[Insight-users] NonUniformBSpline vnl_svd error

[Dennis Jen]

Hi,
  I've run into a problem while using the NonUniformBSpline class.  
While trying to compile, I get the following error where I call the 
ComputeControlPoints method:

  Is there an easy way around this or alternate cubic spline classes in 
itk?  At the moment, I'm just looking to use a cubic spline 
interpolation on a number of points and resample on a finer scale.
  Thanks,
    Dennis
