I want to read the binary data of a fits file. The binary part consists of 23 columns and 1403695 rows. I've tried for instance:
>>bindata=fitsread('filename.fits','binarydata'),
but the only thing I get is a 1x23-vector containing: "[1403695x1 double]". How can I extract the actual data from the file?

Your result is a cell array, one element per column. bindata{17} would be the 17th column for example.
You might want to use
binarray = cell2mat(bindata);
to get an N x 23 numeric array, provided all of the columns are the same data type.
