polarbear sounds really cool, but I can't get it to compile. I get
g++ -DHAVE_CONFIG_H -I. -I. -I. -g -O2 -I/usr/X11R6/include -c -o
PoleZeroEditor.o `test
-f 'PoleZeroEditor.cxx' || echo './'`PoleZeroEditor.cxx
PoleZeroEditor.cxx: In function `void FindCoefs(ComplexArray &, ComplexArray
&)':
PoleZeroEditor.cxx:18: `0' cannot be used as a function
PoleZeroEditor.cxx:23: `0' cannot be used as a function
the code looks perfectly reasonable though - I can't see what's causing the
error. gcc is 2.95.4.
