If date[[i, 6]] == 1 is True, then it will trigger solarcalc[[1, 2]] += solardata[[i, 3]] every time, for every line. That is why all position 2 are the same. Notice that for 'number of minutes' it was, date[[i, 6]] == 1 then date[[i, 6]] == 2 then...
Flatten to join the step column into a flat list. Map to try the BesierFunction for each new step. Export to make a new data file. extraSteps = Map[f, Flatten[step]]; Export["C:\Users\Mitja\Documents\nova\extraSteps.txt", extraSteps,...
Sure. FindMinimum using the starting ellipse coefficients as a search starting point with no other constraints : {res, coes} = FindMinimum[distance, {{aa, a}, {bb, b}, {cc, c}, {dd, d}, {ff, f}, {gg, g}}]; FindMinimum using the starting ellipse...
Once you get the data is the right shape, the next thing you will run into is this message: FindFit::fitc: Number of coordinates (1) is not equal to the number of variables (4). >> FindFit over independent variables labeled {s, w, r, c} will be...
Absolutely. twist = gccolor[{Cos[u] Cos[v], Sin[u] Cos[v], u + Sin[v]}, {u, 0, 2 Pi}, {v, -Pi, Pi}]; Animate[ With[{v = RotationTransform[\[Theta], {0, 0, 1}][{3, 0, 3}]}, Show[twist, ViewPoint -> v, SphericalRegion -> True,...
Straight Import of your data file, may be what is causing sub-lists to become appended. There are a few lower-level functions that can give finer control over how the data is grabbed from the file. These functions are named Read and ReadList. To see...

What you may be looking for there is logical Or for that pair of equalities, double vertical pipe, ||[code]In[ ]:= Cases[Range[1, 100], x_ /; (Mod[x, 2] == 0 || Mod[x, 3] == 0)] Out[ ]= {2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, \...
Gotcha. The rmsd's are being stored in the last position of every vars2 result in errortrial1. If they are already grouped together in the way you want them to be averaged, the rmsd can be isolated specifying multiple levels of Part. Then map...
This example equation (by Frank Kampas) was created using Ctrl+_ to get into Subscript position, right arrow to get back out and Equilibrium symbol entered as Esc equi Esc. Just copy...
