Hello community,

How can I read a binary file? Example of this file is here: http://www.ex.ua/view_storage/614513727428. In *.pdf description about this file is written.

20 bytes - text
17 bytes - text
26 bytes - text and number
2 bytes - number
2 bytes - number
4 bytes - number
...

Maybe someone knows how to read binary file from fixed point, for example, from 74th byte?

Thanks in advance.

With best regards,

Andrew

在 MATLAB Online 中打开

FID = fopen(FileName, 'r');
if FID == -1, error('Cannot open file'); end
fread(FID, 73, 'int8');  % Skip 73 bytes
% Or: fseek(FID, 74, -1);
% Now the further FREAD commands come here...
fclose(FID);
