I am reading a binary file with a structure. Matlab takes long and I wanted
to run Julia for speed improvement.
It reads camera frames, each with certain bytesize and each frame
consisting of parameters of certain byte size and Type.
frames: is declared Int64 and runs from 1:frames

Hi,
I am trying to read a binary file by doing the following:
read(fid, DataType[i], Numelements[i]).
I would like to extract DataType from a user input which is read from a
column (whose header is 'type') of DataTable which is a string array.
For example
DataTable[1,:type] = "uint8"
Thanks James for pointing it out. It did work.
Is there a need for a C++ like function fseek in that case at all?

Or is there a way to replace the column of strings with Types? When I try
to do that I get an error about convert i.e. cannot convert string to
DataType...
Thanks

Is there an fseek in Julia which returns to an offset from the beginning of
the buffer during a binary file read?
Would seekstart followed by seek or skip work? I understand that stream is
not the same as file in read()?
Thanks
I was wondering if a 'median filter' algorithm is available in Julia? There
was some discussion on this topic in 2013. Wonder if someone built it
eventually. I am looking for something similar to medflt1 of Matlab.
Thanks

Hi,
I have two questions.
First question:
I have a fairly simple problem which can be solved in many ways.
To begin I have a vector
z1=Array(Float64,1,0)
I have
Z=1:0.01:100
I would like to generate a vector in which each element is repeated
length(Z) times i.e., [1 1 1 1length(Z)

Hi,
On the Github (or perhaps on the download?) page of Julia there are
instructions as to what you should do when 'make' fails. There is a
procedure for BLAS failure mentioned there.
You have to make a new file if it already does not exist called Make.user
and then type in those commands. Then

Does this make sense. Also I am running this loop only once. I do not
understand why writing in the function form would help. I read the manual
but they suggest writing function form for something which is used many
times.

The error I am getting is
