Re: [sympy] Re: Doing a release

So let's figure out how they do it. Does someone do it by hand, or do they just deal with the conflicts somehow? I'm +1 to doing this somehow, because the current process isn't working. We either need a process wherein everyone updates the release notes with their pull requests (has to be done at

Re: [sympy] Re: Doing a release

SciPy does it too: https://github.com/scipy/scipy/tree/master/doc/release and the notes seem quite comprehensive and well organized. To avoid merge conflicts we could require a single file for each item in the notes to be added and then a script compiles the full note set from those. Jason moore

Re: [sympy] Multiple types of Coordinate Systems for Vectors

Hi, I have submitted a PR which implementes classes *CoordinateSystem* (Super class for remaining coordinate systems), *CartesianCoordinateSystem* and *SphericalCoordinateSystem* using Metric and Lamè coeffecients here . Can you

@Kalevi thanx for response. Actually, I wanted to make a program to form extended euclidean representation of two polynomials(under a field ) so positive integral coefficents is necessary as far as I can see. setting field =True was not able to solve it. just out of curiosity, what effect does

Re: [sympy] Re: Doing a release

Do you know how pandas generates those files? Are they generated programmatically or by hand? Usually having a single file for release notes gets to be a nightmare because of the merge conflicts. Aaron Meurer On Wed, Jan 11, 2017 at 1:46 AM, Shekhar Prasad Rajak wrote: > I think, it will be easy

Re: [sympy] Derivatives with respect to vectors and matrices expressed as vector and matrix operations

Your example is taking the gradient of a scalar function |x2-x1| and getting a vector function. See - https://en.wikipedia.org/wiki/Gradient My geometric algebra package - https://github.com/brombo/galgebra can take the gradient (vector derivative) of a multivector function of which scalars an

[sympy] trunc () result

trunc(2*x**3 + 3*x**2 + 5*x + 7, 3) gives result : -x**3 - x + 1. is there some way to get coefficents positive instead of negative (i.e. here soln be like: 2*x**3+2*x+1)? -- You received this message because you are subscribed to the Google Groups "sympy" group. To unsubscribe from this gr
