Indexing a mapped tensor after permutation

[rpina61]

Hi,

First off, fantastic utility and much appreciated. Makes handling my 5-10GB data sets so much easier than the rather clunky and slow Matlab native memmapfile. I am using the MappedTensor version from Matlab File Exchange. I have a particular use case wherein I permute my tensor, and then attempt to populate with some values. Simple example:

mt = MappedTensor(100,200,10);
mt = permute(mt,[3,1,2]);
[nr,nc,nf] = size(mt);
mt(:,:,1) = randn(nr,nc);

This gives the following error ...

Error using mapped_tensor_shim
*** mapped_tensor_shim: In an assignment A(I) = B, the number of elements in B and I must be the
same.

Error in MappedTensor>mt_write_data (line 1837)
hShimFunc('write_chunks', hDataFile, mnFileChunkIndices, vnUniqueDataIndices, vnDataSize, strClass, nHeaderBytes, cast(tData, strClass), double(bBigEndian));

Error in indexing (line 598)
mt_write_data(mtVar.hShimFunc, mtVar.hRealContent, S, mtVar.vnOriginalSize, mtVar.strStorageClass, mtVar.nHeaderBytes, tfData, mtVar.bBigEndian, mtVar.hRepSumFunc, mtVar.hChunkLengthFunc);

Should I be accessing the permuted tensor differently? Any help would be appreciated.

Cheers,

Robert
