| The following code asks to display the number 1.23001 with 4 digits precision: ScientificForm[1.23001, 4] (* "1.23" *) In my opinion, it is displayed with 3 digits precision. I would prefer it display 1.230 to make the precision... |
| A code for data analysis in use in version 12.0 throws errors in version 12.1. I tracked the issue to version 12.1 generating graphics which appear to have an incorrect dimension . Below are two code segments with the same code executed in the two... |
| # Introduction This Mathematica code determines the component values for a low-pass active filter implemented using the Sallen-Key architecture. The filter will be a second order Chebyshev filter of type 1. This filter offers a steep cut off at the... |
| The documentation for BodePlot lists FeedbackType as an option. It states that for BodePlot[lsys], lsys is wrapped in a feedback loop before plotting, with the default being negative feedback. When I read this I was horrified -- Why would I want... |
| This post is a summary of a problem identified in a longer post on Mathematica StackExchange which can be found [here][1]. The issue identified is inaccurate numerical simulation provided by the function OutputResponse applied to a... |
| It looks useful, but . . . . Plot the Arg of a complex expression: tf = 1000/(s + 1000); Plot[Arg[tf /. s -> w I], {w, 10, 100000}, PlotRange -> All, ScalingFunctions -> {"Log", "Linear"}] ![enter image description here][1] ... |
| I have been using Mathematica 11.3 to analyze experimental data in the form of FITS format images. In 11.3, Import[filename] evauated to an image. In 12.0, it seems to evaluate to an association: ![enter image description here][1] So this has... |
| I recently installed Workbench 2 on my laptop. I am running Win7 Pro x64. I followed the instructions on the Wolfram site: I installed Java JDK version 8 build 192 (current) Then Eclipse Java IDE 2018-09 version 4.9.0 I then added the Wolfram... |
| In the File menu there is an opportunity to open a file as a package using File/New/Package. That opens a specialized GUI with the option to run and debug code. When we look up documentation on this here is what we get: ![help entry][1] Does... |
| The code below (and attached) creates a hierarchical dataset in which the top-level keys map to a list of associations. The intent is to be able to perform an efficient structured access to data. But my attempts to access the data result in errors.... |
