Since I’ve been using Maxima (circa 2016), I’ve occasionally missed some little feature from matlab and coded up a replacement for maxima, with a corresponding blog piece here at the Maximalist.
Some examples are find(), diff(), pause(), size(), cumsum(), diag(), and a few list indexing utilities. Also a help() utility that mimics matlab.
Here’s a mac file with all of those in one easytoload place: matlabesque.mac
Its help() entry reads like this:
matlabesque.mac contains:
find(exp)
ithruj(L,i,j)
indexby(L,indexlist)
matlab_diff(L)
pause([options])
cumsum(l)
size(M)
diag(M)


for any of the above functions,
help(function_name) returns help lines for function_name
