[Ifit-users] iFit bug :)

[Emmanuel FARHI]

Hi Sandor,

The allocation a(2)=iData(..) should work if 'a' is already an iData array.
It does work on the iFit 1.3 release I have...

Alternatively you can write

 >> a=[];
 >> a=[ iData(rand(10)) iData(peaks) ];

The labels can be made 'TeX' like by setting the Interpreter to TeX 
(right click on a label in edit mode (with the Arrow tool from the 
toolbar). The symbol for 'xi' is '\xi', not '/xi'.

Thanks for using iFit and reporting, Emmanuel.
