v1.2

Support for reading PLY, STL, OFF geometry files (vertices/faces). Improved import of text/ascii files containing numerics. Standalone iFit distributable software. Speed-up by a factor x2.5. New iFunc model objects. Improved Optimizers and fitting. Reading of Chalk River CNBC data files, improved recursive reading of sub-directories and handling of iData arrays. New colormap plotting method. Improvements in the Optimizers/McStas plotting. Speed up by +12% (March 16th, 2012)

v1.1

new methods (save, diff, hyperbolic functions), fix of the Levenberg-Marquardt optimizer, improved Error propagation for unary operators, support for import of Analyze MRI (hdr/img) and Crystallographic Binary File (cbf) format, import post-process for HDF RITA2@PSI files, direct drag-drop data files using the open{ext} functions with Matlab >= 2010, added many fit models including 2D functions signal=f(x,y). Improved speed by e.g. +25% (Feb 14th 2012). significant performance improvements (speedup by factor 2-10). (Oct 24th 2011). new fit criteria (others than least-square), link as external/distant resources, better INX import anchor in file names for selective import, plenty of new fit functions, a few bug fixes (e.g. McStas 2D labels). (Sept 22nd 2011). McStas data files with Parameter member. New waterfall plot stype for 3D data sets (Sept 6th, 2011). Added correlation function method, plus a number of minor improvements (esp. in plot contextual menus), and bug fix for McStas 1D data set import (August 26th 2011)
