使用Matlab fit NonlinearLeastSquares for Python,开发人员可以轻松地进行非线性数据拟合。它提供了一系列的函数和工具,用于定义拟合函数、设置拟合参数、选择拟合算法等。开发人员可以根据自己的需求选择合适的拟合方法,并根据实际数据进行参数调整,以获得最佳的拟合结果。
The parameters of fit were determined by using a nonlinear least-squares fitting based on the Marquardt`s algorithm. The program takes into account of low energy tail and escape peaks. The program was employed for the analysis of PIXE spectra of geological and biological samples. The peak areas...
