07 Jun 2011 BIPFIT Fits a bipolynomial of prescribed orders to a data matrix. Author: Vassili Pastushenko Albornoz, Jose

Simple but effective!
22 Jan 2010 SURFIT Approximation of a matrix via an optimal bipolynomial of user-defined orders. Author: Vassili Pastushenko Ulrich

Thanks a lot. I searched ages for something simple to remove a linear planar fit from my 2d matrix. And now I can even easily remove higher polynomal orders. I use it before doing image crosscorellation with the dftregistration.
20 Sep 2009 SAVFILT Generalization and improvement of SGOLAYFILT(Dat,1,Frame). Author: Vassili Pastushenko Simon, Jan

You can accelerate the processing by ~30%, if you replace the lines:
  81: BEGIN=DatF(1:2:W,:);
  ...
  95: DatF=DatF.*WEIG;
with:
  w1 = transpose(1:2:W);
  iw1 = 1 ./ w1;
  iw1C = iw1(:, ones(1, C));
  BEGIN = DatF(w1, :);
  ENDIN = cumsum(Dat(R:-1:R-W+1, :));
  DatF(HW+2:R-HW-1, :) = (DatF(W+1:R-1, :) -
         DatF(1:R-W-1, :)) .* (1 / W);
  DatF(1:HW+1, :) = BEGIN .* iw1C;
  DatF(R:-1:R-HW, :) = ENDIN(w1, :) .* iw1C;
Kind regards, Jan
13 Feb 2008 SWIDDER virtual 2D-slider virtual 2D slider for GUI integer or float, NaN below minX, minY Author: Vassili Pastushenko Min, Shih

Less than 2nd rate. Why bother with this, if VP can't be bothered to make it easy to use? Not a uicontrol anyway. Just as easy to use use ginput if you must create a new figure window.
13 Feb 2008 INTERPOL Standard quadratic and cubic interpolation, and cubic with (improved) continuous derivatives. Author: Vassili Pastushenko Kincaid, Georgina

No better than the interpolation tools already in matlab.

The help looks like it was written by a third grader. Not worth reading the impenetrable help to figure out how to use this to interpolate.
