13 May 2009 find_cross.m, version 2.1 Find and/or estimate level crossings using a combination of search and interpolation. Author: Phillip M. Feldman

Phillip, please have a look at findX.m (File ID: #23860).
http://www.mathworks.com/matlabcentral/fileexchange/23860

It is based on find_cross.m but with an optimized code, completely vectorized, without the restriction of column vectors and with some new features.

31 Oct 2011 polyfit3 Fit polynomial to data, with new features as forced to zero coefficients and data weighting. Author: Antoni J. Canós Kan, Andrey

thank you for a useful implementation.

memory usage of this function can be reduced by replacing lines:
W=diag(w);
WV=W*V;
Wy=W*y;
WVfull=W*Vfull;

with the following code:
W = repmat(w, 1, size(V, 2));
WV=W.*V;
Wy=w.*y;
W = repmat(w, 1, size(Vfull, 2));
WVfull=W.*Vfull;

just what I was looking for

14 May 2009 Fast and Robust Self-Intersections Computes the self-intersections of a curve. Author: Antoni J. Canós Beardmore, Robert

It certainly is very good and saved me a lot of bother!!
