| I would like to know now Mathematica changed from 13 to 13.0.1. Any Wolfram links that would tell us? |
| Mathematica's parallel processing is very good for the right task. But I have been watching Mathematica use all 6 processors of my i7 chip with 6 kernels and thinking what about the other idle 6 threads? My license is for 8 subprocesses (kernels)... |
| I coded processing for race data where the position of a competitor is published as n/m. That led to passing the data as published like this - score[n_Rational] := score[Numerator[n], Denominator[n]] ; That worked (for a non-linear... |
| Benchmarks were run on Win 10, 32GB, i7 5820 (6 cores), same machine same month. - 12.1 Performance = 2.45 - 12.2 Performance = 2.28 Complete benchmark results (System Comparisons and Detailed Timings) attached as notebooks. Anyone... |
| I viewed on YouTube [Formatting the Wolfram Language][1]. The presenter said that 12.2 may have already been released by the time of viewing (I viewed it!). The Mathematica online documentation already has [Summary of New Features in 12.2][2]. I am... |
| Is it possible to extract the data points from a RandomInstance? I have generated pictures, but would like to know the coordinates of the points to check the computations and possibly see if potential assertions were ever tested for validity. |
| The function **InverseFourierSequenceTransform** returns a Piecewise function. The display of the values is nice but the values are buried in the representation. I got along by descending the expression tree for the values, but today the expression... |
| I have a list of symbols ` {sym1,sym2, sym3,...}` I would like to have Mathematica build the list `{HoldForm[sym1],HoldForm[sym2],HoldForm[sym3], ...}` The purpose is to build a list for use in Switch. to allow print of the symbol associated with a... |
| I have some very large Trig expressions that I want to analyze. On one of these TrigFactor listed -2 Sin[\[Beta]/2 - \[Gamma]/2] Sin[\[Beta]/2 + \[Gamma]/2] then I did In[56]:= Simplify[-2 Sin[\[Beta]/2 - \[Gamma]/2] Sin[\[Beta]/ ... |
| I've been running Mathematica with large amounts of data. ByteCounts for lists can be over a gigabyte. Sometimes seemingly small software changes could put Mathematica into a virtual memory fit leading to system lockup. *(A related problem is that... |
