- changed implementation of gamma and related functions (using boost.math now)
- syntax: so-called parametrized-functions spline[] and interpolate[]
- are replaced by so-called variadic functions Spline() and Polyline().
- The GUI in the Baseline Mode handles a separate baseline for each dataset now.
- abandoned syntax like 5
New in Fityk 0.9.2 (May 8, 2010)
- To compile fityk, Boost (only headers) and xylib must be installed first.
- Fityk tarball does not contain a copy of boost and xylib now.
- user-defined functions: split functions can be defined in this way: SplitG(h, c, w1, w2) = x < c ? Gaussian(h, c, w1) : Gaussian(h, c, w2)
- added info-numeric-format option
- a couple of bug fixes
New in Fityk 0.9.1 (May 3, 2010)
- added cfityk to Windows installer
- changed output of "info errors", see the manual for details
- GUI: "plot in @n" changes selected datasets (useful in scripts)
- many bugs fixed
New in Fityk 0.8.9 (Oct 16, 2009)
- manual was converted from DocBook to reStructuredText
- GUI: On Linux fitting was very slow, this was fixed. A new option `refresh-period` was added to control refreshing during fitting.
- define supports variable substitution with "define ... where ...", e.g. define Foo(alpha) = alpha * eta * (eta / tanh(eta) - ln (2*sinh(eta))) where eta = 2*pi/alpha * sin(theta/2), theta=x*pi/180
- added access to symmetric errors from scripts (e.g. $variable.error or %func.height.error)
- category "Education" was added to fityk.desktop
New in Fityk 0.8.8 (Oct 16, 2009)
- added two flags to the configure script: --with-xylib and --with-samples (xylib from the fityk tarball is not used by default now)
New in Fityk 0.8.7 (Jun 22, 2009)
- fityk license was changed from GPLv2 to GPLv2+ (2 or at your option any later)
- all config files are stored in a single directory:
- Unix: ~/.fityk
- Windows: C:Documents and SettingsusernameApplication Datafityk
- Mac: ~/Library/Application Support/fityk
- This changes the path to the default and alt. configs on Windows and Mac.
- now works also with GCC 4.4 and Boost 1.35
- minimum wxWidgets version increased to 2.8.0
- added functions LogNormal and LogNormalA (Mirko Scholz)
- abs() can be used in user-defined functions
- added syntax for loading data from all columns in file: file.csv:1:2..::
- bug fixes, most notably bugs with saving/loading session
