_______________________________________________________
Details:
When one saves a single precision matrix with matlab binary format (tried
both -v6 and -mat7-binary) the matrix is upcasted to double precision. If one
does this in matlab, however, the matrix will remain single precision when
reloaded (and while on disk). Furthermore, there is no documented option in
save that allows saving of single precision matrices in any matlab binary
format.
