Details:
"save -v7" isn't able to write data to file if the data is larger than in the
order of ~100-150 Mbytes (according to "whos").
As the data question (here a 1x1 struct) contain nested structs, struct arrays
and small cellstr arrays and double arrays it may be a bit larger than "whos"
reports.
"save -v6" goes fine; the size of the .mat-file on disk more or less equals
the size reported by "whos" (e.g.,
Attr Name Size Bytes Class
==== ==== ==== ===== =====
D 1x1 584238640 struct
... leads to a file of 574,963 KB.
Needless to say Matlab happliy runs the same code fine and creates fairly big
.mat-files w/o issue; the above struct becomes a 127 MB file.
According to the Matlab docs the difference between -v6 and -v7 is merely data
compression and Unicode support.
Octave has no issues reading a big mat-file created by Matlab with -v7 option;
it is specifically writing to file that goes wrong.
If required I can upload the .mat file somewhere.
