Details:

Hello,
As suggested by JWE, here's a report about issues with available variables in
nested scope. The idea is to initialize some context with a few constant
matrices and some variables.

The expected behavior is to get a new result from a matrix operation after
test_nested_script lines 6 and 7, where the increase() and decrease funcs are
called.

Under MatLAB R2018b, the test "exist('x', 'var')" succeeds and the size of x
is displayed: (2, 1) for ctr1 and (10, 1) for ctr2. Under Octave, the behavior
w.r.t. n and n0 is OK, but variables 
"A regmat x y" are not available in the subfunctions.

Platform= CentOS 8 stream, gcc-8.4.1, compile options 
"--without-qt --without-qscintilla --enable-address-sanitizer-flags
--disable-float-truncate --disable-docs"

Regards

Pascal
