I am unable to reproduce this problem either.

% echo 'which rcond' | octave -q
'rcond' is a built-in function from the file libinterp/corefcn/rcond.cc
% echo 'rcond(magic(31))' | octave -q
ans =  0.030391

I get the same output whether octave-ltfat package is installed or
not. Could the OP please show the output of
% echo 'which rcond' | octave -q

both before and after the octave-ltfat package is insalled? That would
at least confirm which rcond is being called.

FWIW, here are the packages I have installed.
