AWStats has a config file. Its extension usually is .conf. There I found the following information: # By default, AWStats only records info on 404 'Document Not Found' errors. # At the cost of additional processing time, further info pages can be made # available by adding codes below. # Change : Effective for new updates only # Example: "403 404" # Default: "404" Hope this helps Albrecht

It works for me. I tried: ratsimp(invert(matrix([a11, a12], [a21, a22]))); and got: Warning: WITH-COMPILATION-UNIT is being redefined. [ a22 a12 ] [ ----------------- - ----------------- ] [ a11 a22 - a12 a21 a11 a22 - a12 a21 ] (%o4) [ ] [ a21 a11 ] [ - ----------------- ----------------- ] [ a11 a22 - a12 a21 a11 a22 - a12 a21 ] For your information: wxbuild_info()$ wxMaxima version: 13.4.0 Maxima version: 5.31.1-1 Maxima build date: 2013-09-28 13:02:56 Host type: i686-pc-mingw32 Lisp implementation...

draw2d(fill_color = red,fill_density=0.6,buildq( [x:barlist], bars(splice(x))),xaxis = true); Does this what you want?

Hello Mirco, how about defining your own function that performs this transformation? E.g. like this: foo(f,e):= f*ratexpand(ratsubst(1/sigma[m],a*k/(2*mu[0]*p[0]),ratexpand(e/f))); foo(2*a,n/d);==> 2*a*(1-sigma/sigma[m]) Regards Albrecht

PS: Note that Maxima is case sensitive: Simp and simp are different variables!

Hello Mirco, I think you are right: simp is only a variable like any other - except for the fact that Maximas simplification mechanism checks the contents of this variable to decide if simplification should be done or not. You may want to read the chapter "Introduction to Simplification" in the Maxima manual to learn more about this mechanism. Unfortunately I did not notice that I used the wrong name in the explanation. Sorry for the confusion I caused. You should see a difference in row %i6. When...

Hello Mirco, I think there are two separate problems: a) Maxima usually simplifies its result. So even if you succeed to create the form you want Maximas simplifier will modify the result. So you may not see the result you expect. b) How can you tell Maxima the exact form you want? Ad a) There is a variable that allows to turn off the simplification process. With simplification turned off you have to call simplification functions yourself. To turn off simplification use subst:false Ad b) As I understand...

A little thing I forgot: If you are in need for speed try calling the "compile" function on your functions before calling them. Using a compiled version of your code may speed up things.
