[patch]: Fix tests/tutorial/matlab_iter_example.cpp

[Jules Bergmann <jules@xxxxxxxxxxxxxxxx>]

Adds a test_write function to create the sample.mat file necessary for 
the read tests.
There is a race between this and the other tutorial/matlab test if 
they're run in parallel.  Fortunately, the release testing is serial (sigh).
Patch applied.
