Thanks for your reply.
I have already read the manual again, and use the R.dll (Ch 8.2.2) (Am I
right?). Running the example in the section is OK. But, when I try to add
"do_matprod" function in the same example, I don't know what args should put
in. The function description in array.c is SEXP attribute_hidden
do_matprod( SEXP call, SEXP op, SEXP args, SEXP rho), and where I can get
the definition and description of each variables, call, op, args, ....
Thanks,

This is indeed in the manual you mention. To use R functions and not just
standalone libRmath, you need to embed R.
