Category: Lisp Core  Integration Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: integrate function raises "too many contexts" error Initial Comment: When I try to run the following command sequence f1c_2d:x^2*y^2*\(sin(2.*x)+%i*cos(2.*y))*exp(%i*20.*x)*exp(%i*30.*y)$ l:integrate(f1c_2d,x,1.,10.); l:integrate(l,y,5.,15.); I get a "too many contexts" error message after the second call to "integrate". I use maxima 5.15.0 with SBCL Lips. The function to integrate is pretty easy so I do not expect that there is an error at all. regards Eugen Wintersberger eugen.wintersberger@...
