Is there a Julia package that implements parametric splines? I noticed that the Dierckx Fortran library has an implementation but the corresponding Julia package does not does not have bindings for it. Thanks, Kaj

[julia-users] How does "pass-by-sharing" work exactly?

As a new user I was surprised that even if you change the value of function arguments (inside the function) the changes are not always visible outside but in some cases they are. Here's an example: function vappu!(a,b) a[3]=100 b = b .+ 5 (a,b) end c = [1:5] d = [1:5] vap

Hm, but the idea is to write an in-place modifying function...in fact it might be a good idea to look how the ! functions are implemented. On Thursday, May 1, 2014 3:28:58 PM UTC+3, Freddy Chua wrote: > > don't even pass it to a function, just do > b = b .+ 5 > > wherever you need to. > > Shoul
