 Dec8 awarded Caucus Sep17 comment How to decompose N into A and B so that A and B are close to each other. Is this to be done on a computer? You could take the floor of $\sqrt{N}$. Jul6 comment Numerical Integration Over Two Regions of an Ellipsoid I have revised this question and posted it on the Computational Science forum as suggested: scicomp.stackexchange.com/questions/13051/… Jun29 asked Numerical Integration Over Two Regions of an Ellipsoid Jun18 awarded Yearling Jun2 comment Extracting angular velocity tensor from orthogonal matrices @linello How did you obtain the formula for $\omega$ in your comment above (sept7'11)? I am trying to solve the equation for $\mathbf{x}$ in $\mathbf{Y}$ but cannot reach your solution. Jun1 comment Extracting angular velocity tensor from orthogonal matrices @joriki When solving $\mathbf{Yx=x}$, how do we know that we obtain the correct direction $\mathbf{u}$ and not the opposite direction $-\mathbf{u}$? Jun1 comment composition of rotation matrices @Muphrid I have modified the question to indicate the order of the angles and emphasize that there is no intended conversion between extrinsic and intrinsic rotations. Jun1 comment composition of rotation matrices @Rahul I have modified the question to reflect that the rotation is to be applied to the left on column vectors. Jun1 revised composition of rotation matrices addressed comments Jun1 revised composition of rotation matrices addressed comments May31 asked composition of rotation matrices May30 revised Euler-Angle convention grammar May28 answered Euler-Angle convention Feb14 awarded Excavator Feb14 awarded Organizer Feb14 revised Given a set of rotation matrices, is it possible to determine the rotation conventions employed? The question has been stated more clearly in the title and in the body of the text. The matrices therein have been written in standard MathJax, converted from pasted Mathematica Code (this is not a Mathematica-related question). The conventions have been rewritten more conventionally. Feb14 suggested approved edit on Given a set of rotation matrices, is it possible to determine the rotation conventions employed? Feb5 answered Discretize an ellipsoid given its semi-major axes and orientation Feb4 comment Discretize an ellipsoid given its semi-major axes and orientation @RahulNarain Yes.
