If sum of "k" or/and "l" is more then 7 I have problem with reading
vectors (cols)

You're missing the `fid`. You have to tell it where (which file, or which
group)
you want to create that dataset.
--Tim
Tim , thx for hints, but do not work without this line
#fid["mygroup/A"]=rand(2)
becouse I vave not "g" , and nothing to declare in this line /dset =
d_create(g, "F", datatype(Float64), dataspace(10,10))/
/
dset = d_create( "F", datatype(Float64), dataspace(10,10))/
do not work ...

That line just means 'create a variable called "A" inside a group called
"mygroup", and assign it a value of rand(2)'. If you don't ne
Thx, Tim,
I have solution but is 2 questions:
1. Whay must be line: /fid["mygroup/A"]=rand(2)/ ?
2.if sum k and l > 9 Julia cant work. Is it to big size for hdf5 or for

using HDF5
hfi=h5open("bigfile.h5","w")
close(hfi)
k,l=6,3;
fid = h5open("bigfile.h5","r+")
Big Thx for big lesson, is no too "dark" now

Thx, form me this moment
*hfi["mygroup/A"] = A*
was not too clear

You can also work directly with the HDF5 file as an array object...
using HDF5
hfi=h5open("myfile.h5","w"); # create the file
close(hfi)
A = reshape(1: 120, 15, 8);
hfi = h5open("myfile.h5","r+") # read/write access
hfi["mygroup/A"] = A
15x8 Array{Int64,2}:
1 16 31 46 61 76 91 106
.
Of course, first I read :)
Is there about reading range array. I need to save a range of In analogy to.
A = reshape (1: 120, 15, 8)
h5write ("/ tmp / test2.h5", "mygroup2 / A", A)
data = h5read ("/ tmp / test2.h5", "mygroup2 / A" (2: 3: 15: 3: 5))

If I understand correctly, then yes, that's possible. See the HDF5 docs.

How to overwrite to an existing file, only range of data?
In HDF5 can do this?
I have an array of zeros 10 x 10
I need an existing file owerwrite range rand (5x5), for example.
Existingfile [2: 7.3: 8]
