That's the way I do it, but you might try DDE (on Windows). I have
a DDE interface to Matlab in iForth, and I think SwiftForth and VFX 
have one too. (It's slightly more challenging than box4.)

The interface spec. of these two words is:

S" FORTHCMD" m2f{  MAT@[EMAIL PROTECTED]
 \ copy FORTHCMD matrix from Matlab to FSL-style
Forth dmatrix
newcmd{ S" NEWCMD" MAT! \ copy FSL-style dmatrix to Matlab NEWCMD (must
exist)

Of course, you also want S" aap" MEXECUTE (let Matlab execute Forth
command),
but I didn't use that in the posting.
