In the following code using R2012b, the Tiff object keeps allocating more internal memory with every read.
t = Tiff('file.tiff')
for i=1:n
t.nextDirectory
imagesc(t.read)
end
t.close
Closing the object frees the memory at the end. But is there a way to clear the memory for frames which have already been displayed without closing the object?

I see the same problem in 2013b. I would think this is a bug or an undocumented buffer. At the very least we should be able to disable that buffer.

It turns out that if you open the tiff in 'r+' mode. There is no buffering/memory leak. I am going to file a bug report on this.
