| In[667]:= seq = {a, b, c, d} (* make "c" green" *) Out[667]= {a, b, c, d} (*recover "c" as green in color*) |
| I exported a long list of fractions to a .dat file using "Data". They import fine, but have a Head of List. I can't even use N[ ] on them. What format should I have used so the fractions are immediately usable? |
| I would like to take a long list of numbers, scale it to 20 - 20,000, and play it in Hz for about 0.1 second per list element. I see functions for notes, but not for Hz (in cycles per second). |
| If I bundle instead of going parallel, would anyone have sample code of multiple computers running Mathematica in terms of naming and exchanging files, starting a process on another computer, and watching for computations to be completed? |
| Here are three ways to solve a singular matrix: PI is SVD - always works - scales bad: cubic on CPU, square on memory CAM is a kludge - sometimes works, but not in this example - scales great YI is a short-cut SVD - always works - scales... |
| If I already know that I need 10 gB of memory for a particular matrix calculation, can Mathematica be told to find sufficient resources in a parallel computer before the calculation even begins? Will it take and hold another nodes RAM from the getgo... |
| I have a brand new pi. I think they recommend NOOBS first. What OS should I install to be compatible with Mathematica? Any other advice for a pi nubie? |
| Is there a 'fit to page' option for .nb? How do you keep your matrices on page - not running off margins? |
| list1 is X values list2 is Y values The x and y values in each are in order with each other. Can I get ListPlot to assemble these two lists as x,y points in a scatter plot? I don't see the option. |
| a.b See elements being multiplied and added rather than just the solution? |
