Well, I don't see much value in replacing the Maxima user
language with Matlab syntax. I guess it is a little more well-known
but it's an ad-hoc language just like Maxima's.
However one feature of Matlab that I find very useful is the
submatrix-indexing stuff, e.g. a[i, :] yields all elements in a row
and a[:, j] yields all elements in a column, x[L] yields selected
elements where L is a list of zeros and ones. I think there are
maybe one or two other such constructs. I attempted to replicate
that in Maxima, with some success, in the amatrix add-on package
which I committed to maxima/share/contrib, but replacing the lone
colon with the symbol 'all, and the 0/1 selection by false/true.
