Hi, I am a new to Julia, and I need some help.

```
% Load data in Matlab
fileID = fopen('./data_6000x3199.bin');
Data = fread(fileID,[6000,3199],'single');
fclose(fildID);

```

How can I convert this simple code from Matlab to Julia?

I don’t know the `.bin` format — if you can describe that, it is more likely that you will get help.

If it is just a bunch of `Float32`s, it may be something as simple as

```julia
data = zeros(Float32, 6000, 3199)
read!("data_6000x3199.bin", data)

```
