[julia-users] row of a matrix

It seems that the way Julia handles A[1,:] changed in v0.5. *julia> **A = [1 2 3; 4 5 6]* *2×3 Array{Int64,2}:* * 1 2 3* * 4 5 6* *julia> **A[1,:]* *3-element Array{Int64,1}:* * 1* * 2* * 3* *julia> **size(A[1,:])* *(3,)* A[1,:] used to be a row-vector in v0.4 same as in

[julia-users] precompiling all packages

Is there a way to precompile all packages at once? Each time that I run Pkg.update(), I would also like to precompile all packages so that when I actually use packages I don't need to precompile. Chang

[julia-users] Re: scope of variables when using include

Thanks, Jameson. That means, I have to actually write bar(y) within the function foo(value), right? I have foo(), foo1(), foo2(), foo3(), all of which use the same bar(y). Should I repeatedly write the code for bar(y) for all foo functions? Is there any other way? I can make the bar()
