New to Julia
1

hi, im new to julia. coming from matlab.

im just trying the language out, just playing with it before jumping in completely.
i cant get DelimitedFiles to work, to simply read a txt file.
When i type:

using DelimitedFiles
Coor=readdlm("test.txt")
print(Coor)

i get:

LoadError: ArgumentError: Cannot open 'test.txt': not a file

in expression starting at untitled-8ead38e87ae54c024af70d734f3fca9a:3

#readdlm_auto#9(::Base.Iterators.Pairs{Union{},Union{},Tuple{},NamedTuple{(),Tuple{}}}, ::Function, ::String, ::Char, ::Type, ::Char, ::Bool) at DelimitedFiles.jl:233

the file “test.txt” is a simple matrix 4x4

Welcome!

That error just means that your file is not located in Julia’s current working directory (whatever directory the julia command was run from). You can check Julia’s working directory with:

pwd()

To open a file in some other directory, you can either use its full path:

readdlm("/path/to/your/files/test.txt")

or you can change the working directory:

cd("/path/to/your/files")
readdlm("test.txt")

In REPL

; cd /path/to/your/files

works also.
