| I just got the notice from Customer Service regarding the newly available Workbench as an Eclipse plugin. The Wolfram instructions say to install JDK8 and Eclipse Neon before installing the plugin. I get to the point of installing Eclipse and the... |
| I'm trying to do something which should be simple: Cause the current date to be printed in the header. Under File>Print Settings>Headers and Footers there is a nice form, and to the right an arrow that opens selections, just to make it easy. For... |
| I am working with a system of differential equations in an algorithm which requires repeated solution using NDSolve. There are currently over 300 equations which are both differential and algebraic. The system is highly nonlinear and can be somewhat... |
| I have been trying to form a query in MMA11 for data for all counties in the US. Apparently, one must first acquire a list of the states and territories, use that to query for counties, and then use the full list of county entities in the final query... |
| Given a hierarchical data set, I am looking for a way to extract a list of values by their keys. When I use the Part syntax for a single key, I get the value. But when I use a list of keys, I get a Dataset. Is there a succinct way to get a list of... |
| Hello, I have been interfacing to another program using the .NET interface, and found that real values which at their source have at least 7 digits of precision are being rounded. That lead me to read them as strings and apply ToExpression, with the... |
| I am doing a long computation and wanted to use a 2nd kernel to continue working interactively in a new notebook. I followed the instructions given here: http://support.wolfram.com/kb/12425 But any attempt to launch the new kernel, either... |
| Log plots are very useful for visualizing scientific and engineering data. We need more of them -- like LogListContourPlot, Log10ListContourPlot, LogListPlot3D and Log10ListPlot3D. I am sure we can do this ourselves, and handle all the scaling and... |
| 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... |
