How to use CMATMPY intrinsic

Hi,

I'd like to know how to use the cmatmpy intrinsic.

I read in "TMS320C6000 Optimizing Compiler v7.4" that the intrinsic is __x128_t_cmatmpy (long long src1, __x128_t src2);

I'm really new at this and I don't understand how it works... I tried _cmatmpy(array,matrix); but it doesn't match with the types of the arguments.

Can you clear that up for me please ?

Thank you,

Alex
