File read and fill matrix in boost, cpp

[guven]

Hi,
I have following set of code

using namespace std;

using std::vector;

include <boost numeric="" ublas="" matrix.hpp="">

include <boost numeric="" ublas="" io.hpp="">

include <boost numeric="" ublas="" operation.hpp="">

using namespace boost::numeric::ublas;

boost::numeric::ublas::matrix<double> A_MATRIX(10,10);

int main(){

int i,j,temp1,temp2;
    double temp3;

ifstream ptrReadCtvtxt;

ptrReadCtvtxt.open("ctv.txt");

for(i=0;i<10;i++){

    for(j = 0; j < 10; j++){
        if(j==0){
            ptrReadCtvtxt >> temp1;
            if(temp1>maxCtv)
                maxCtv=temp1;
        }
            if(j==1) ptrReadCtvtxt >> temp2;
            if(j==2) ptrReadCtvtxt >>temp3;             
        }

           A_MATRIX (temp1-1)(temp2-1)=temp3;

}
ptrReadCtvtxt.close();

return 0;

}
When I build, I receive this error for line A_MATRIX (temp1-1)(temp2-1)=temp3;

error: no match for call to ‘(boost::numeric::ublas::matrix, boost::numeric::ublas::unbounded_array > >) (int)’

I appreciate any help. Thanks a lot

PS: I am sure, temp1, and temp2 values are within bounds of matrix.
