I saw that eye has been deprecated in Julia v0.7. The message that appears is: Warning: `eye(m::Integer)` has been deprecated in favor of `I` and `Matrix` constructors. For a direct replacement, consider `Matrix(1.0I, m, m)` or `Matrix{Float64}(I, m, m)`. If `Float64` element type is not necessary,…

I think this is extremely unfair to the contributors, and I doubt you follow the PRs and issues very closely when you make these claims and statements. We actually have very active contributors who mostly do documentation (and tests!). Ofc, there is always more to do, but there are actually people w…

[image] airpmb: I also get the sense that any time the devs have a chance to expunge Matlab idioms from the language, they take it. Whether or not it’s accurate, you see the result–what is the issue that you have with it? It seems you attributed that quote to the wrong person. I do quite a…

[image] Per: (I wish that they’d gotten rid of the hard-coded f' = adjoint(f) as well.) Yikes! What would you suggest instead?

Why should we fully adopt MATLAB idioms? Isn’t it because we think it is not perfect and then we have the Julia language? eye is not explicit, you won’t notice which type you are using. I will vote for IMatrix if we need something for identity matrix rather than eye. If we have eye(3) You cannot …

Why hard-coded f' = adjoint(f) is annoying? Is there any example for this?

[image] pkofod: I think comparing their work to that of janitors is not really fair I don’t think there is anything wrong with being a janitor, and I have in fact often heard that title used in a respectful way about people who do a lot of important, low-profile work. While I agree with much…

In finance and econometrics, there’s often a fair number of I_n (eye(n)) floating around in the papers/texts. Since I like my programs to stick closely to the “theory,” this carries over to my attempts to code. In the run up to 0.7, I spent some time purging eye from all my code for my lecture note…

[image] stillyslalom: To be clear, I don’t have an issue with the changes themselves (except for linspace , RIP. linspace(0, pi ) is so much nicer for interactive use than range(0, stop=pi, length=50 ). This is temporarily worse than it will be in the future. With the deprecation removed in 1…

Ok so maybe rather than just my specific suggestions of contributing to the Wikibook and working on a MatlabToJulia.jl (or modernizing MatlabCompat.jl) is anyone interested in forming some sort of MATLAB/Julia users SIG which can do these sorts of things (including others’ probably better ideas than…

Count on me! 99,99% of the engineers at INPE (National Institute for Space Research) use MATLAB and an easy update path is required :slight_smile: I think MatlabCompat is fine. But we need to make it come back to life.
