MATLAB: Why the empty cell array taking 104 bytes instead of 112 bytes..

Hello,

it is mentioned in the document that,

an empty cell array will take

30 bytes for 32 bit systems

& 112 bytes for 64 bit systems.

i got confused why my 64 bit system is taking 104 bytes of memory for an empty cell array..

can someone please explain me..?

Thanks in advance ..!

A = {[]}

is NOT an empty cell, it's 1 x 1 cell contains an empty array.

An empty cell is

A = {}

z(cellfun('isempty',z))=[]

Do you really mean byte by byte? The variable read conatins 16 bit characters of the text as unicode, so a byte by byte conversion is:

read = '|0|01|00|5e|'
typecast(uint16(read), 'uint8')

The original text might be a ASCII text, then import it as bytes directly:

fid = fopen('packettext.txt', 'r');
if fid < 0, error('Cannot open file.'); end
bytes = fread(fid, inf, '*uint8');
fclose(fid);

Maybe you want to import the numbers and convert them from hex to decimal?

S = fileread('packettext.txt');
values = sscanf(S, '|%x', [1, inf]);

To clarify this, please post an example with input data and the wanted output.
