Ok, so let me suggest one solution. First, an explanation. When you write:

lib a : ........

this may produce everything -- the LIB itself, response files, various
intermediate files nobody cares about. Most of the time, if you stage 'a' you
want only LIB target to be staged. For that reason V2 marks all targets which
are not of LIB type as intermediate and 'stage' ignores intermediate targets.

There are many ways around that.
1. Tweak .m -> .c .ctf generator so that it marks .cft as not intermediate
2. Write a new main target 'matlab-lib' which does the same
3. Specify that CTF files are to be staged in the 'stage' invocation (not
possible in CVS state, but I have various solution around).

>From user's point of view, the first approach is the simplest, because it
requires the least work. I attach an implementation. Basically, it just
defines a new generator and overrides the 'generated-targets' method, which
is responsible for actually creating the result.

Let me know if that works for you.

Jamfile is
exe a : a.m ;
stage x : a ;

and project-root.jam is

import m ;

rule generated-targets ( sources + : property-set : project name ? )
local r = [ generator.generated-targets $(sources) : $(property-set)
: $(project) $(name) ] ;
# Clear the 'intermediate' flag on third target (of type CTF)
# so that whenever ".m" file is present in sources of any target
# the CTF target will be considered real result of the target,
# and will be staged as well as other files (like exe)
$(r[3]).set-intermediate ;
return $(r) ;
generators.register [
new mex-generator m.mex : M : C(%_main) C(%_component_data) CTF ] ;

actions mex
touch $(<) ;
