[julia-users] Re: IPython keeps giving Kernel error

What happens when you open up the Julia command line ("REPL" ... i.e. double-click on the Julia program in Mac or Windows) and type Pkg.update() Pkg.build("IJulia") If there is an error message in the second step, that should be a clue. If not, relaunch `jupyter notebook` and try again. On

For the bitstypes, you can do `[read(fh, UInt16)]` to be a bit more concise. On Wed, Sep 30, 2015 at 12:31 PM David McInnis wrote: > Sorry for the slow response, was called away. > > As a starting place I'll try to stick with the builtin routines first. > With Stefan's idea

RE: [julia-users] Re: What's the reason of the Success of Python?

When you have matrices with special structures and symmetries, Julia can encode that information in the type of the matrix, and in those cases the backslash operator should actually be more efficient than in Matlab because there is no need to “guess” what the best algorithm might be. My

Re: [julia-users] restricting the type of bitstype type parameters

There are potential advantages for the system to be allowed to construct these types so that it can reason about them, even if it can't create instances of these types. See for example https://github.com/JuliaLang/julia/commit/85f45974a581ab9af955bac600b90d9ab00f093b#commitcomment-13041922 Doing
