Re: [sage-devel] Re: How to write packages of sage

Thank you,Kcrisman. I am so sorry that I did not ask my question clearly, but luckly you understand most of my question. The link to publication that use sage is great. I do hope sage can have a lot of packages like R. It seems that sage focus on pure mathematics more than application.I do not fi

Re: [sage-devel] Re: Faster roots computation for Sparse Polynomial

Following your advices, I have created a ticket (#16516 ) on trac, and pushed a modification. I changed the Polynomial.roots function to look at the return value of _roots_univariate_polynomial and I added a method _roots_univariate_polynomial to IntegerRi

Re: [sage-devel] Re: How to write packages of sage

In fact,I like the pure math part of sage.But it would be better if I can do some modelling on sage. Recently I was reading the reference manual of probability, but I found that RealDistribution does not support normal distribution. RealDistribution supports uniform, gaussian,rayleigh,lognormal,

Re: [sage-devel] Re: How to write packages of sage

I am so sorry that I forget about this as the 'gaussian'distribution in sage only take one parameter sigma. I think 'normal' distribution should have two parameters mu and sigma. Kannappan Sampath 提到： >On Tue, Jun 24, 2014 at 8:28 PM, gofortu...@gmail.com >wrote: > >In fact,I like the pure m

Re: [sage-devel] Re: cube roots in Sage

As Vincent and Niles have brought up, there might be advantages to it being a symbolic function. How does one actually go about making that happen? Is this an intrusive change, or an easy one? I really have no idea... ---Greg On Sun, Jun 22, 2014 at 5:00 PM, Vincent Delecroix <20100.delecr...@gma
