Hi
I have a data file logged in binary. I would like to read this data into Matlab to plot and perform analysis.
My question is: Can one directly define a struct in Matlab and then cast a array of binary data to it? This is easily achieved in C, but I cannot find an equivalent means in Matlab.
The alternative is ofcourse to pack each field in the struct individually, but the problem with this is that there are several structs within the data, each with 20+ fields!
Thanks in advance,
Amir

No, MATLAB struct fields each have separate data areas.
You should look at memmapfile

I have the same problem and data comes from a tcpclient so I can not use memmapfile. Is there an easy way ?

There is no easy way.

or look in the file exchange with keyword "serialize"
