Details:

in v2018b, Matlab added the 'all' option for a number of functions.  

This was mentioned related to another missing option in:
https://savannah.gnu.org/bugs/?func=detailitem&item_id=58089#comment1

which states it applies to "all, any, bounds, max, min, mean, median, mode,
prod, std, and var".

This was noticed on the mailing list regarding the sum function when a new
user tried to port over some code.

while bug #58089 was about a the option where the functions take a vector
dimensions for multiple summation, the "all" function should be fairly trivial
to implement as:

if "all" --> A = A(:), continue sum operation

At first glance at the function list it looks like this approach should apply
to them all.
