This is a bug that I'll have to look into. The dimension seems to get
lost. I'll also have to fix an earlier problem with writeMat()
existing in R.matlab v1.2.2 and later. See archive how to install the
latest stable version v1.2.1. In the meanwhile you can do something
like:
writeMat(filename, list(A=A, dim=dim(A)))
and reassign the dimension manually in Matlab (I don't know how that's
done though).
FYI, readMat() is way more stable/tested than writeMat(). The only
redundancy tests I can do on writeMat() is to try to read the data
back in using readMat(). I have little time to load writeMat()
written *.MAT files in Matlab.
