On p. 586 of the manual, it is claimed that MathExec("expr") evaluate[s] expr
as Mathematica input, and return[s] the result as a string.
On the sun 4 1.1 version (though mathlink.c is in common so I expect this
is true everywhere), there is no mechanism for returning the result to the
user program that I can see. And it doesn't seem to work. (I can get
MathExec to work, it just doesn't return anything)
I haven't seen anything anywhere about this. Ideas?
More generally, how does one pump a lot of numbers efficiently into the
user program, i.e. suppose one wants to send a 50 by 50 matrix from Mathematica
to the user program. I don't see how the mechanism of Section B.7.6 allows
this except through MathExec() as above (which looks kludgy but doable if
it worked).
