series(gamma(x),x,0,2); collect(series(gamma(x),x,0,2),x); -EulerGamma+x*(1/12*Pi^2+1/2*EulerGamma^2)+x^(-1)+Order(x^2) -EulerGamma+x*(1/12*Pi^2+1/2*EulerGamma^2)+x^2*Order(1)+x^(-1)
The other bug is with the fraction free elimination in ginac/matrix.cpp: If I try to solve the system [[ [[0,2-a]], [[5-4*a,3+2*a]] ]] * [[ [[x]], [[y]] ]] == [[ [[-2+5*a]], [[-5-2*a]] ]] I run into trouble within assert-blocks. I will have a look at the second problem. -rbk. -- Richard Kreckel <Richard.Kreckel@Uni-Mainz.DE> <http://wwwthep.physik.uni-mainz.de/~kreckel/>
