20140205 07:02:57 +0200  asked a question  build sage without documentation I see that sometimes when building sage with the commands the majority of time is employed in building the documentation. Actually I'm not interested in building the documentation on my machine (I usually have an internet connection and I usually browse the documentation online). Is it possible to ignore the documentation when building sage? How can I do that?

20120820 13:33:30 +0200  asked a question  Caching sagetex results Is there a way to cache computations already done in a latex file using sagetex so that, for example, if I add a Sage code line in The best thing would be that when one uses sagetex, Sage remembers what formulas are already computed and stored in foo.sout, and recomputes them only when they are modified. Do you think it's possible? Thanks!

20120309 10:48:57 +0200  answered a question  3d plot ignoring imaginary part I just get to a solution by myself... My problem was the impossibility to plot because of numerical errors that turns my (expected) real values into complex numbers with an imaginary part extremely small. I used the fantastic function "list_plot3d". For example: It's not difficult to modify the above code if one wants to really ignore complex numbers while plotting (that is indeed what Matlab automatically does).

20120307 12:33:08 +0200  asked a question  3d plot ignoring imaginary part Is there any possibility to have a 3d plot done in a way that if the expression to be plotted returns a complex number, this is not plotted. In particular I'm referring to this feature in Matlab: when you try to plot in 3d an expression which in his domain has both real and complex values, it returns the plot only when the values are real. In addition Matlab prints a Warning: "Imaginary parts of complex X, Y, and/or Z arguments ignored". Thanks! (tell me if it's not clear, I'll explain better...)
