Re: The concept of a record

I know this part of knowledge about Fortran. My question should have
been put this way: with X written out as in the example, what shape
would it be of the matrix A = fread(fid)? Here fread is the matlab
command. For a matrix in matlab, the shape (n,1) and (1,n) look
visually differently, although internally they may both be stored as a
sequence of numbers in the memory. It turns out that the matrix has
the shape (n,1).

The shape is not written into the file by Fortran. Most likely they
come out (n). That is, a 1D array, but I don't know matlab enough
to say. If you write an n by m array in one unformatted WRITE
n*m elements will be written, again without any shape.

In R, one can change the shape after they have been read. I presume
matlab can do that, too.
