Constrained nonlinear least squares fitting

Title of program: CNFIT
Catalogue Id: AAXQ_v1_0

Nature of problem
Many high energy physics experiments require fitting of particle tracks. In particular, one often has to (e.g. OPAL at LEP) fit a curve to a set of points (xi,yi,zi),i=1,...,N each of which is a function of two measured independent quantities.

程序标题：CNFIT
目录编号：AAXQ_v1_0
问题性质：众多高能物理实验需对粒子轨迹进行拟合。特别是，在诸如LEP中的OPAL实验中，常常需要对一组点（xi,yi,zi），i=1,...,N进行曲线拟合，其中每个点均为两个测量独立量的函数。
