   <text:p text:style-name="equation">This method is better than the guide point method. Unit matrix for W seems ok. But there is an optimum W. Here too dlam increases with each iteration. Why? But the dsI and dsJ diminish properly.</text:p>
   <text:p text:style-name="equation">I applied this method for SurfaceCurve, but the convergence rate was very slow.</text:p>
