Implementation of the nonlinear leastsquares method with apriori twosided limitations on variables is given. The optimization GaussNewton scheme was used. The linear equation systems which appeared m the problem were solved using orthogonal matrix transformations which allowed to considerably reduce requirements to information representation accuracy. It is shown that imposing twosided limitations on the parameters of the approximating function is a rather powerful stabilizing factor extending the convergence domain of the nonlinear leastsquares method based on the GaussNewton method.
