Re: [julia-users] Using -args to execute a function for different parameters

There are a few doubts that I may want to clarify as of now. Thanks a lot for the link @Yichao, @Josef. 1. The function definition in python is def main(argv). I wrote function main(args) in the Julia equivalent. Is this the right way to do it? 2. For the line in Python args =

Re: [julia-users] Using -args to execute a function for different parameters

Hi Josef, I shall paste a function that I used for my python files. Would it be okay if I asked you for some help to do the same in Julia? I've implemented most of the code but this still remains to be done in Julia and I wasn't aware such a package exists. Thanks a lot def main(argv):

[julia-users] How to save an object of a defined type

I have a module defined as module *Core* within which I have defined several types (*Node*, *Edge*, *Res*). Now what I intend to do is that I want to save the output of a function which is an object (*res1*) of type *Res* onto a JLD file so that I can retrieve it later on. I am calling the

It worked. Thanks for your advice. Another thing, I observed the previous version v0.4 folder on the disk. Is there a way to delete it and free up some space? On Saturday, 8 October 2016 20:43:57 UTC+2, Yichao Yu wrote: > > On Sat, Oct 8, 2016 at 2:41 PM, Yichao Yu > wrote:

Hi, I'm not sure if anyone else has this problem but apparently, after updating to v0.5, I can no longer find the packages that I had previously installed in v0.4. The console says, argumenterror: Module Statsbase not found in current path. I tried Pkg.status in my pwd and it didn't show any

Hi, I seem to have run into a problem here. I firstly have a function as follows: function gen(type, frame1, frame2) x = frame1[:type] z = frame2[:type] y = [] for i in length(frame1) push!(y, x[i] * z[i]) end end Now, when I call: ans = gen(I, frame1, frame2), I get a

Oh, thanks so much! It fixed my problem. But, is there a way to just write PhyNode(blah, blah, blah) instead of the cumbersome MyClasses.PhyNode ? I tried using MyClasses and it reported the same error as well. On Friday, 16 September 2016 12:11:18 UTC+2, randm...@gmail.com wrote: > > The error

Hello all, I'm making a transition from Python to Julia and in the process, I've encountered a small difficulty. While in python, i declared three classes as follows: class PHY_NODES: def __init__(self, nodeID, nodenum, x, y, demands): self.id = nodeID self.nodenum =
