Getting index from strsplit or strfind in a null (00) terminated string

I have a long string with chunks of data. Each data chunk is separated/terminated by null (hex 00). Right now I use strsplit(data, '\0') to split the string, which works fine, but it returns a cell array with data, however, I rather need the functionality of strfind and get a list of indices for where the string is split.

Example of data:

   data_chunk "null/0x00" data_chunk "null/0x00" data_chunk "null/0x00"

I know the first chunk is obviously at index 0, but I would also like to get the indices of the remaining chunks.

Is it possible to use strfind and search for null?

Post clearly your data, for example:

str='null/0x00'

Then explain what is the expected result

result=?

For reference, an example of the string could be

str = 'engine_thrust combustion yaw pitch roll'

where the whitespaces are char null i.e. hex value 0x00.

What am I missing?

>> str = [char(0),'abc',char(0),'123',char(0)];
>> find( str==char(0) )
ans =
     1     5     9
>> strfind( str, char(0) )
ans =
     1     5     9

>> strsplit( str, '\0') 
ans = 
    ''    'abc'    '123'    ''

You are not missing anything, that is the answer I was looking for. I was not aware that char(0) would yield that result and could be used for the search pattern.

Thank you.

Simon, don't concentrate on that. The char() casting is not needed. This works just fine as you'd expect:

str = [0, 'abc', 0, '123', 0];
nullLocations = find(str == 0)
subStrigns = strsplit(str, '\0')

[Simon]

Great, nice to know, might as well keep it as clean as possible.

IMO: Explicit casting makes the code easier to read (and often faster).

>> ['B'+1, 67]
ans =
    67    67
>> ['B', 67]
ans =
BC
>> ['B'+1, 'C']
ans =
CC
