This tool-box is a set of m files for data analysis tasks such as curve fitting, some mathematical functions such as elliptic integrals, function minimisation and a few general-purpose functions. These are work-horse functions designed to make moderately advanced methods easily available. For example, integ is fast and precise, slf alerts the user in the case of poor fit, amsfit is flexible, findpeaks is robust, etc. The functions address three main areas: working with experimental data, optimisation, and tasks such as integration and inversion when you don't have the explicit function, only evaluations of it (or data points). Some powerful numerical methods are employed, but without detailed treatment of special cases. Some of the methods are taken from Numerical Recipes, 2nd ed (W. H. Press, S. A. Teukolsky, W. T. Vettering, B. P. Flannery, Cambridge 1994). Thanks also to S.C. Webster for some of the atomic physics. ## Highlights
