[sage-support] plot color computet by function
Hey, i need some help. I try to definde the mandelbrotset with colors defined by following function: sage: def mandel(x,y): v=[];c=x+y*i;z=c;v.append(z) for m in range(30): if abs(z)2: z=z^2+c;v.append(z);color=exp(-m) return color Then i typed: plot3d(0,(x,-2,2),(y,-2,2),rgbcolor=hue(mandel)) Now i get TypeError? May anyone has an idea? Thanks for help Danjo -- You received this message because you are subscribed to the Google Groups sage-support group.

[sage-support] Re: Keeping rational functions simple throughout gaussian elimination
I have no idea whether SAGE supports this, but basically what you need is fraction-free Gaussian elimination: See section 3.2.3 of http:/staff.bath.ac.uk/masjhd/JHD-CA.pdf On Wednesday, 22 August 2012 13:04:08 UTC+1, Erik Aas wrote: I'm trying to solve a system of linear equations over the field Q(x1,...,xn) of rational functions in x1,...,xn. The system is Ax = 0 where A has entries from the field and has rather large size (500 rows and columns for example). One way to do it is to compute kernel(A). In my case it is 1-dimensional. The basis vector returned has coordinates of the form (polynomial/polynomial + polynomial) / (polynomial - polynomial) et.c. Calling .denominator() and .numerator() on the expression does not terminate before my patience does. Is there a way to make sure the equation solver keep all coefficients on the form polynomial / polynomial? -- You received this message because you are subscribed to the Google Groups sage-support group.

Re: [sage-support] boolean to binary conversion?
ok thanks did not know about that at all. So I spend an hour on figuring out 10 lines of code to do the same thing. figures lol.
