But I have to admit that this kind of empty variable is not yet covered by the test. In [matio_test_cases.m](https://sourceforge.net/p/matio/matio_test_datasets/ci/master/tree/matio_test_cases.m) we have the following cases for empty cells ``` %%...

Again, it all is about the undocumented opaque type for MCOS.

Confirmed, the design of the `mat_sparse_t` structures is broken w.r.t. the dimension types. Furthermore, there is no need to store `isComplex`, `isGlobal`, `isLogical` and `mem_conserve` as int32 in `matvar_t`. This...

Which leaves the question, what to make the default case.

Related to #98.

The opaque type is not well supported. At least it does no longer crash (after 3b6dc8fcbe39e45b01b3dcbab253593390c07a93).

I am very interested in such a performance benchmark. Do you think you can share your code and the MAT file you were using such that I can try to...

Thanks for the code snippets. Based on them I've created https://github.com/tbeu/matioPerformance which compiles with VS 2012 - the same VS version that the MATLAB R2015b libraries were built with. libmatio.dll...

I am expecting the three performance bottle-necks * structs and cells handling * decompression/inflate handling (e.g. there is no inflateCopy called by the MATLAB mx API) * file I/O where...
