I worked with Sign[Sin[Exp[x]]] for simplicity. Integrate fails here as it does in your example, without really letting the user know. Plot[{Evaluate[Integrate[Sign[Sin[Exp[x]]], {x, 0, k}]], Sin[Exp[k]]/Abs[Sin[Exp[k]]]}, {k, 0, 4}] ![plot...
A force diagram (tension excluded) can be shown nicely for the grass example, as the dynamic forces are defined directly from equations of angular derivatives, and thus have already been calculated. This also helps stress how easy it is to play with...
I've deduced that if a C compiled function references another C compiled function at export, the sub function is exported to .c with it. This represents a large part of the functionality I was inquiring after, but it does raise further questions. ...
The Reddit math forum [turned up][1] this [nice site][2] of sudokuish Garam puzzles yesterday. Fill in the blanks. ![A Garam puzzle][3] Someone was quick to post [their Mathematica reduction][4]: ![enter image description here][5] They...
FromDigits /@ Partition[RandomSample[Range[9]], 3] yielding {319, 584, 276} The power here is doing your randomisation before you cut the data up into substructures.
Awesome project; the write up is particularly impressive! It can be hard to give good structure to a lengthy post in this format. Have you worked at all with lower level control of the drone, or interpreted its lower level data? I've an ongoing...
I put this together [needing][1] a FindShortestTour equivalent for points in Euclidean space. Clearly that route blinded me to FSTs conventional use in a graph context! This is completely untested on graphs and likely doesn't work. In the...
I'm interested in motion capture data. We understand musculature, yet motion capture remains a tool used only for skeletal animation. I suspect proper interpretation of mocap data could create tools for diagnosis. To extrapolate muscle interaction...
Lovely post Michael! A certain immediacy and intuition seems to be prerequisite in games made today. Why would the average customer choose high investment entertainment over a lower one? I think this has done a lot of damage to the strategy games...
In my last post I was struggling to generalise the transition I'd chosen from five points to six. It felt slightly too neat that the progression continued back to a regular tetrahedron. Reversing the change, we see a transition pulling a duplicate...
