Given a matrix A I need to compute the eigenvector matching the dominating eigenvalue. In 0.6 I used v = eigs(A, nev = 1, which=:LM) I cannot find anything similar in 1.0. How do I compute this eigenvector without computing all the others (as e.g. eigen does)?

It got moved out of Base to Arpack.jl: using Arpack ... v = eigs(A, nev = 1, which=:LM) FWIW, 0.7 gives you the following more-informative error message: ERROR: eigs has been moved to the package Arpack.jl. Run `Pkg.add("Arpack")` to install it, restart Julia, and then run `using Arpack` to load …

[image] PSA: use Julia 0.7 if you are upgrading Announcements A lot of people are posting issues where their old code doesn’t work anymore on 1.0 because some function has been renamed or removed. The 0.7 release exists exactly for this reason: your old code will work on 0…

Oh I see, sorry for the noise :blush:

New to Julia, have version 1.3 So to figure out the new name of a function, I would need to install julia 0.7 ? I keep running into this issue, and currently search the web for ‘julia <old_function_name> deprecated’ Is there a better way to handle this? I am having no luck finding what realmax(Fl…

In general yes - using that function on 0.7 will give you a message telling you what the function has turned in to: julia> versioninfo() Julia Version 0.7.0 #[...] julia> realmax(Float64) ┌ Warning: `realmax` is deprecated, use `floatmax` instead. │ caller = top-level scope at none:0 └ @ Core no…

I am looking at various notebooks, both to see julia examples and to read up on some algorithms. I am really surprised at the number of deprecated functions, and the difficulty finding replacements. I wonder if a list of deprecated functions and their replacement might be picked up by webcrawlers …

[image] ea42gh: I am really surprised at the number of deprecated functions, and the difficulty finding replacements. You don’t have to worry too much about this if you just started using Julia and using some Julia 1.x version . There were many breaking changes from 0.6 to 1.0 (with 0.7 prov…

Well, there are the Release News for 0.7 which has a list of deprecations as well, but simply running the code in 0.7 will in general be easier than checking that list. As Stefan writes in the post I linked at the beginning of this thread, the 0.7 release exists for exactly this purpose, as it was …

Thank you for the pointer to the list of deprecations!
