Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Satoshi Adachi (satoshi_adachi) Assigned to: Nobody/Anonymous (nobody) Summary: Incomprehensible behavior of coeff(). Initial Comment: Dear Developers of Maxima, I met an incomprehensible behavior of coeff().

However, they are not in actuality. This phenomenon may be a bug of coeff(). Or it may be a part of ``specification'' of coeff(). I cannot judge which is the case. If someone can access some old version of Maxima, which is old enough, he or she can run the above example program by using the old Maxima to get the result by that version of Maxima to compare the result with my result. This may help to judge whether this phenomenon is a bug or a part of specification of coeff(). If this phenomenon is a bug of coeff(), plase fix it. Since this phenomenon of coeff() exists, I had to put an ugly fragment of code in my Maxima program for the workaround.

Category: None Group: None >Status: Closed >Resolution: Fixed Priority: 5 Private: No Submitted By: Dieter Kaiser (crategus) Assigned to: Nobody/Anonymous (nobody) Summary: abs((1+%i)^%i) is wrong Initial Comment: That is the complex number when we evaluate the expression numerically: (%i91) rectform((%i+1)^%i),numer; (%o91) .1548717524642468*%i+.4288290062943678 That is the correct absolute value of the complex number: (%i92) abs(%); (%o92) .4559381277659962 Now the wrong result: (%i93) abs((%i+1)^%i); (%o93) 1 That is the result when we use cabs: (%i94) cabs((%i+1)^%i); (%o94) sqrt(%e^(%pi/2)*sin(log(2)/2)^2+%e^(%pi/2)*cos(log(2)/2)^2) cabs evaluates to the correct numerical result: (%i95) cabs((%i+1)^%i),numer; (%o95) .4559381277659962 Remark: It does not help that cabs gets a correct result. The abs function should give a correct result or no result. I have not studied the bug systematically. I think we have wrong results whenever we have a complex exponent. Dieter Kaiser  >Comment By: Dieter Kaiser (crategus) Date: 20090227 17:03 Message: The proposed fix has been committed. The Example 59 in rtest16.mac has been modified and a test was added to rtest_abs.lisp. Closing this bug report as fixed. Dieter Kaiser  Comment By: Dieter Kaiser (crategus) Date: 20090225 17:44 Message: I have checked the suggested change with the testsuite and share_testsuite. There would be only one problem in rtest16.mac with example 59. We have to add an extra assumption and to remove a rectform and the test will work again.

The Maxima tar ball is supposed to contain the generated documentation (.info and .html files). What does the following show: tar tvzf maxima5.17.1.tar.gz  grep 'maxima\.\(info\html\)$' The intent is to detect maxima.info and maxima.html at the end of a line. You might need to adjust the regular expression. If your tarball does not contain maxima.info or maxima.html files, from where did you get it? If you did not get it from Sourceforge, you might obtain the tarball from the Maxima download page and try again. If your tarball does contain the generated documentation, make should not be trying to build it. If make is trying to build existing files, come back and leave another comment and we'll go from there.

Villate (villate) Summary: legend does not work Initial Comment: Here's a simple example: plot3d(x+y,[x,3,3],[y,4,4],[legend,"Line"]); I get "y+x ___________" instead of "Line" for a title/legend? I cannot get the title to use legend? If I have an expression name instead of a function, I get the generic title of "Function _________". At least [legend, false] works, but I'd like to put titles in my graphs. Thanks. Lester  >Comment By: Robert Dodier (robert_dodier) Date: 20090225 11:09 Message: Appears that legend works OK for plot2d but not for plot3d. I'm assigning this report to the person who was last working on the plot options.  Comment By: Lester Ingber (ingber) Date: 20090216 14:45 Message: P.S. I'm using Maxima under Cygwin on a Thinkpad with XP Pro. This seems to be a gnuplot option. I could not get legend to work with other gnuplot options which do work fine. E.g.: plot__smni_Lag:if abs(smni_Lag) > 1.0 then 0 else smni_Lag$ plot3d(plot__smni_Lag,[ze,80,80],[zi,30,30],[gnuplot_term, ps],[gnuplot_out_file,"c:/cygwin/home/ingber/smni_Lag.ps"],[xlabel, "M_E"],[ylabel,"M_I"],[zlabel,"L"],[legend,"smni_Lag"],['grid,40,15])$ Lester  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=2607007&group_id=4933

Presumably the principal values is what is wanted. I will correct that. This is related to the fact that carg(exp(%i*x)) doesn't normalize x to (pi,pi] when x is not an explicit multiple of pi: carg(exp(%i*10)) => 10 carg(exp(%i*x)) => x but carg(exp(%i*(3*%pix))) => %pix How far should this go? I think it's pretty clear for the float/bfloat case, but how about carg(exp(%i*10))? Should that really return 104*%pi?
