v1.5.0.3

v1.5.0.3

New features

1. add argument callable for models plotting and their conversion to TF1. It allows to draw some derived quantitites

bw = Ostap.Math.BreitWigner( ... )
bw.draw ( xmin = ... , xmax = ... ) ## draw the Breit-Wigner lineshape
bw.draw ( xmin = ... , xmax = ... , callable = lambda x : bw.amp ( x ).real ) ## draw real part of amplitude
bw.draw ( xmin = ... , xmax = ... , callable = lambda x : bw.amp ( x ).imag ) ## draw real part of amplitude
bw.draw ( xmin = ... , xmax = ... , callable = lambda x : cmath.phase ( bw.amp ( x ) ) ## draw the phase 

1. add tiny utilities lrange and log_range (in addition to existing vrange) into ostap/utils/utils.py

for x in vrange ( 0.0 , 10.0     , 10 ) : print x  ## "lin-range"
for x in lrange ( 1.0 , 10.0**10 , 10 ) : print x  ## "log-range"

1. add methods amp_real, amp_imag, amp_phase for the Breit-Wigner-like models
2. add Argand plot for the Breit-Wigner-like models

bw = Ostap.Math.BreitWigner(... )
ap = bw.argand ( xmin = ... , xmax = ... , npx = 500 )
ap.draw('alc')

1. add utilities for better visuzalisation of Dalitz densities
2. more improvements for Dalitz plot vizualization
3. more tweaks for Ostap::Math::DalitzIntegrator
4. more tweaks for Ostap::Math::BW
5. add bb ("bounding box") method for ROOT.TGraph-like objects.
6. more tweaks for ROOT.RooMinimizer, in particular better control over printout

Bug fixes:

v1.5.0.2

v1.5.0.2

New features

1. Simplify interface for Ostap::Math::Integrator and Ostap::Math::DalitzIntegrator classes: essentially remove large duplication, the tag/label argumetn for caching is now the last one and "optional"

Backward incompatible changes

Bug fixes:

1. fix a bit strange "feature" with "derived" variable in RooDataSet (thanks to Alexander Artamonov for rereporting). It happens that RooDataSet::addColumnRooDataSet::addColumns` behave a bit differently. the first one issues the error message and variable behaves weirdly.
