In the most simple case this may look like A(w). I can make plots using different statements like plot_semiogx, or plot(...,scale='semilogx') etc, but the results look odd. Apparently the internally generated points on the x-axis lways have a linear distribution. Only forcing an exaggerated number of points (e.g. plot_points=100000) results in a correct graph. I didn't find a better solution. I think the plot command should distribute the x-points in a log-fashion automatically for semilogx and loglog plots, thus I consider this a bug. I'm using sage 6.2 right now. Any ideas how to workaround/fix this?
w = var('w')
A0=1e7
w0=100
A(w)=A0*(1/(1+i*w/w0))
plot_semilogx(abs(A(w)),1,1e7)gg@gSat, 27 Sep 2014 15:32:32 +0200https://ask.sagemath.org/question/24310/
