subtract 1

Hi Jonath:

Here is another bug I found. The following Matlab script when converted there is an error.

Matlab: J = zeros(6,12); X_kk = ones(3,3); J(1:2:end,[1 4 7]) = -X_kk';

C++ (wrong):

int main(int argc, char** argv) { mat J, X_kk ; urowvec _aux_urowvec_1 ; J = arma::zeros(6, 12) ; X_kk = arma::ones(3, 3) ; uword __aux_urowvec_1 [] = {1, 4, 7} ; _aux_urowvec_1 = urowvec(__aux_urowvec_1, 3, false) ; J(m2cpp::span(1-1, 2, J.n_rows-1), _aux_urowvec_1) = -arma::trans(X_kk) ; return 0 ; }

C++ (correct):

int main(int argc, char** argv) { mat J, X_kk ; urowvec _aux_urowvec_1 ; J = arma::zeros(6, 12) ; X_kk = arma::ones(3, 3) ; uword __aux_urowvec_1 [] = {1, 4, 7} ; _aux_urowvec_1 = urowvec(__aux_urowvec_1, 3, false) ; J(m2cpp::span(1-1, 2, J.n_rows-1), _aux_urowvec_1 - 1) = -arma::trans(X_kk) ; return 0 ; }

The _aux_urowvec_1 should subtract one from it.

Thanks.
