| Hello all, The attached notebook and data file demonstrate a problem with FindMinimum. The data is a set of points which to a great extent lie on a circle. The calculation attempts to find the center of the circle by locating the point which is... |
| In the evaluation below, I want both y[t] and y'[t] sown by StepMonitor, but for some reason y[t] is sown unevaluated. It appears from the output that the derivative is taken after t is replaced by its value like y'[t->value], rather than... |
| I believe the attached file ran without errors in 10.2, but in 10.3 In[8] results in: sol = NDSolveValue[equations /. values, {x[t], y[t]}, {t, 0, 500}]; NDSolve::depdole: The differential order of a dependent variable in... |
| Several recent posts have remarked that it would be useful to have a general form of BinLsts which could bin a list by means of a function applied to the first level, similar in principal to SortBy. After some thinking, it occurred to me that... |
| Today I loaded and evaluated a simple notebook I saved yesterday. When the evaluation got to a Histogram statement it stopped and displayed "Updating from Wolfram Research server" for about a minute. I'm running 10.3 on Windows 7 x64. I thought... |

| I just installed 10.3. Here is the result of running the WordDefinition function exactly as it appears in the docs: In[3]:= WordDefinition["dolphin"] During evaluation of In[3]:= CreatePaclet::badppi: The paclet... |
| Below is code which is supposed to create a window with a graphic, and then refresh is every 3 seconds until the Control "run" is unchecked. It creates the window and does the continuous refresh, but unchecking "run" has no effect. Can any of you... |
| It's Friday, 9/25/2015 9:27AM on the west coast, and the dashboard is well out of date. Only a couple of posts within the past 24 hours show up. Posts I have email about are not present. If I look for those in "My Discussions" they don't show in... |
| I have been looking for the syntax needed to display a graphic (this one produced by ListPlot) in a new window, and do so repeatedly, each time replacing the new window contents without creating an additional new window. I would like also to generate... |
