How can I read text file with number of elements in each line is different?

I have an input text file:

result.txt:

0
[0
0
0
3,19,24,44,47
0.17221,0.26928,0.1476,0.2485,0.16241]

I used load function in matlab to read it (load('result.txt')), but I couldn't. How do I read this file?

Thank for your help!

None of the standard data importing routines can handle that file because of the '[' and ']'. You could use textscan for part of it, but it probably is not worthwhile doing so. It would be easier to use fgetl() and sscanf(), or to use fileread() and regexp() .

You have not defined the desired output variables. MATLAB numeric arrays cannot have different numbers of elements per row, so if you want to preserve the structure you will need to use multiple variables or you will need to use cell arrays,

Thank for your answer! Sorry, I haven't described clear input. I attached result.txt. Can you see it? How can I read this file? I want to preserve the structure. In this file, I store vertices in odd rows, I store weight of corresponding verhices in even row. After load this file, output that I need like this: 3 19 20 24 44 47 0.17221 0.26928 0 0.1476 0.2485 0.16241 0.33 0 0 0 0 0 0 0 0.6 0 0 0 I attached file output.txt Can you help me? Thank for your help!

Why is the entry for 20 last when 20 is the middle series?
