Hi,
Just use
TF1 *t[2];
t[0] = new TF1("g","gaus",-6,6);
t[1] = new TF1("p","pol1", 0,6);
Or better yet, use a container instead of a C-style array (TObjArray, TList
or the equivalent stl container).
Cheers,
Philippe.

Hi ROOTers,
I desperatelly need to perform plenty of fits of simuilar
functions. I wnated to create table of pointer to plain C functions.
Does not work. Now I want to create an array of pointer to objects.
Does not work. See below. (Seems like parsing of array statement
problem.)
Any idea how to make it.
Regards,
Tomasz Bold
root [0] TF1 *t[]={new TF1("g","gaus",-6,6), new TF1("p","pol1", 0,6)};
Error: Function newTF1("g","gaus",-6,6) is not defined in current scope
FILE:(tmpfile) LINE:1
Possible candidates are...
filename line:size busy function type and name
*** Interpreter error recovered ***
