I want to use Needs
to download the QuickReIm
package to simplify the complex conjugation, but I keep getting errors:
here is the Command:
Needs["QuickReIm`"]
and here are the errors:
Get::noopen: Cannot open QuickReIm`.
Needs::nocont: Context QuickReIm` was not created when Needs was evaluated.
Do you know the reason? Where can I find different packages and their uses?
Needs
does not download anything (please check its documentation). What it does is it loads a package, provided that that package is installed. Downloading the package and installing it is something you need to do yourself before the package can be used. "QuickReIm" is not a standard package. If you have a question about it, you should clarify where one can get this package. $\endgroup$ – Szabolcs Dec 28 '19 at 11:20
