Re: [sage-support] Out of memory error when dividing vector by scalar

2012-07-27 Thread Daniel Smertnig
Indeed, the problem seems to still be present in 5.2rc1. I've tracked the call to basis() back to an inefficient implementation of gen() in FreeModule_ambient (apparently the coercion framework ends up calling an_element() which in turn ends up calling gen()). It seems easy enough to fix. I

I have a symbolic equation that needs to be plotted. example: y |-- x^2 + x + 1. How do I transform it into y = x^2 + x + 1 so I can be able to make a plot? -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to

Hmmh, I have a macbook pro mid 2009, Core 2 Duo. Some Core 2 Duos mis-represent themselves as 64 bit? How could I check wether my machine does that? It used to run under 32-bit, but than I switched it to 64-bit via an official apple command. The systemprofiler states 64-bit... Am Freitag, 27.
