Class Method Details

.new(spline, xa[], ya[]) ⇒ Object

Generate an instance of Numo::GSL::Spline2D::Bicubic class, a subclass of Numo::GSL::Spline2D class with gsl_interp2d_bicubic type.

This function initializes the interpolation object interp for the data (xa,ya,za) where xa and ya are arrays of the x and y grid points of size xsize and ysize respectively, and za is an array of function values of size xsize*ysize. The interpolation object (gsl_interp2d) does not save the data arrays xa, ya, and za and only stores the static state computed from the data. The xa and ya data arrays are always assumed to be strictly ordered, with increasing x,y values; the behavior for other arrangements is not defined.

Parameters:

  • spline (DFloat)
  • xa[] (DFloat)
  • ya[] (DFloat)
