error

[Vladimir Litvak]

I think it depends on your Matlab version. I've had this problem many
times and recompiling with just 'mex read_24bit.c' in Matlab command
line and moving the file up has always solved it for me. Maybe Robert
will have some other ideas. Just to make sure - you really compiled it
from Matlab command line, not with an external compiler?

Best,

Vladimir
