Second Order Differential Equations

This toolbox implements an energy-based segmentation algorithm that usesfinite-difference based level set evolution. (See [1], [2]).Multiscale control of the curve evolution is implemented -- this greatly reducesthe sensitivity to initialization as well as improves the execution speedby factors...

Plot data in a figure, and then interactively choose regression area. The result from polyfit is returned.Example:x=1:1:10;y=sin(x);f=figure; plot( x,y );[p,h] = figreg( f, 2 );%fit a second order polynom to selected region in plot Platforms: Matlab

A common request is to interpolate a set of points at fixed distances along some curve in space (2 or more dimensions.) The user typically has a set of points along a curve, some of which are closely spaced, others not so close, and they wish to create a new set which is uniformly spaced along... Platforms: Matlab
