in older versions in julia, i used the readlm command to read data in *.dat Now, in julia v1.0 , the same code, i have this error UndefVarError: readdlm not defined what should i do ? in older version of julia, the code works fine ! now, in julia v1.0, give this error I use the INTERPOLATION…

Julia 0.7 tells you the answer: julia> readdlm WARNING: Base.readdlm is deprecated: it has been moved to the standard library package `DelimitedFiles`. Add `using DelimitedFiles` to your imports. in module Main readdlm (generic function with 6 methods) julia>

thanks … works fine … now, do you know what is this problem ? when i try to plot something, the error linspace not defined how can i solve it ? and how can i use: t=[0.1:0.1:2pi] s=sin(t) plot(t,s)

Exactly the same answer: use 0.7 and get the answer.

Well, in this case 0.7 doesn’t give any warning. I would try: t=range(0.1,step=0.1,stop=2*pi) s=sin.(t) plot(t,s) Notice the dot after the sin . No guarantee that this works, couldn’t test it.

hello … thanks a lot … works fine … but … i have, for example — tt=range(0.1,step=0.1,stop=2*pi) s(t)=sin.(t) for t in tt plot(t->s(t),tt[1],tt[end]) end how can i do that?

Do you want me to do your homework? :face_with_raised_eyebrow:

it is not howework kkk … but in julia v0.7 pyplot does now work … it be fix in julia v1.0 but thanks a lot ! if you have time, help me … thanks

[image] PSA: use Julia 0.7 if you are upgrading Announcements A lot of people are posting issues where their old code doesn’t work anymore on 1.0 because some function has been renamed or removed. The 0.7 release exists exactly for this reason: your old code will work on 0…

0.7 does give a warning: julia> linspace(1,2) ┌ Warning: `linspace(start, stop)` is deprecated, use `range(start, stop=stop, length=50)` instead. │ caller = top-level scope at none:0 └ @ Core none:0 1.0:0.02040816326530612:2.0

So replace linspace with range. Any problem?
