Details:

Hi,

I am trying to load a fairly large .mat file created by Matlab and I'm getting
a lot of errors like those shown below

using octave 3.4.2 and java-1.2.8

eg.
error: load: invalid element type = 0

zero is very common 65535 also and raft of less frequent values.

Do these numbers actually represent something related to "data element type"
or are they spurious values output because octave is incorrectly parsing the
data?

ie does this mean I have a dozen formats that are not supported or probably
just one ?

If it's just one I may have a go at fixing it or getting the data in an
acceptable format.

Shouldn't Octave be trapping this a bit better?


There seems to insufficient information to know what it can't handle and to do
something about it.

Also I have seen allusions to this issue that some formats are not yet
supported but there seems no list of what is and isn't supported that would
enable to work around it.


It would seem better if this incompatibility was at least properly documented.
