v5.3.0

Full Changelog: v5.2.1...v5.3.0

add HDF4 h4{size,exists,variables}

remove h5ndims, ncndims

flatten namespace

speedup functions

• h5exists, ncexists: 2x-100x speedup
• stem, read_symlink: string Posix output
• use isSymbolicLink, createSymbolicLink if available.

add numerous functions

add is_symlink, create_symlink, read_symlink.

ncsave: require dimensions for non-scalar

add sys.cpu_count, touch, get_modtime, set_modtime, relative_to(), proximate_to, is_subdir, filesystem_type()

is_absolute_path => is_absolute

require scalar non-empty inputs, add functions

add exists(), is_readable(), is_writable(), sys.cpu_load(), sys.ram_free(), sys.ram_total() all using Java internal to Matlab.

require scalar non-empty inputs to simplify internal code.

add several functions, distinguish canonical from resolve, bugfixes

add function fileio.{parent,stem,filename,suffix,join}

distinguish function fileio.canonical() which returns relative path if not exist from fileio.resolve() that always returns absolute path--if not exist, absolute based on cwd.

expanduser: ignore inputs like ~abc

subprocess_run: correct high level interface nargout and improve test

absolute("") = ""

Internals use posix filesep "/" throughout

Test: shortname: test with Matlab exe so it's always present (vs. notepad)

Java-based functions, add normalize

• add normalize() function
• use mostly Java-based internal functions for fileio

remove redundant code

v4.10.1

remove redundant code

improve tests and correctness. Add several stdlib.* aliases

v4.10.0

ci: add R2023a

add sys.wsl* functions

for Windows Subsystem for LInux add functions under stdlib.sys

h5save: add shape checks

to avoid confusing errors, check the shape of "sizeA" vs array size, if given for h5save
