Hi all,

I’m trying to do the following matrix multiplication in the transformed parameters block: K2[C] = A[C,C] * K1[C] for several samples S.

transformed parameters{

vector [S] K1[C];

vector [S] K2[C];

matrix [C,C] A[S];for (s in 1:S) {

K2[s] = A[s] * K1[s];

}

}

A is supposed to be a one dimensional array of size S containing C × C matrices and K1 and K2 arrays of size S containing vectors of size C.

I’ve tried many ways to do that, but they all result in error. I’m happy to provide more information if needed.

Thanks
