In this case the unit tests blocks must be preceeded by a return
statement.

isequalwithequalnans does not exist in Octave 4.2 and both Octave and Matlab encourage use of isequaln

Print PASSED or FAILED for each tested routine.

If m-unit-tests/src is in the Matlab/Octave's path, then

help m-unit-tests/src

will display the list of routines in the toolbox and an example.

To use this toolbox the src folder should be added to the Matlab's path
and the script src/initialize_unit_tests_toolbox should be executed (if
needed the missing subfolder will be added to the path).

Wrong arguments passed to reshape() routine.

Output argument t was not initialized when dassert() routine was called
with three arguments for comparing arrays of doubles.

First input of isa() routine is the tested object, not the type of the object...

Propagate the correct number of input arguments in recursive calls.

Missing condition to decide which version of isequal should be used.

Added comparison of struct and cell arrays (with recursive calls).

The routine get_directory_description only returns m files in the
targeted directory and subfolders.
