Delete range from multidimensional array (vector)

 
Hi All
I hope you are well and safe. Could you please help me to delete an item from a multidimensional array? For example how can I delete the first range of in_matrix below?

----------------------------------------------------------
vector<CArrayInt*> int_matrix;

for(int i=0;i<10;i++){
    CArrayInt *int_vector = new CArrayInt(); 
    for(int j=0;j<10;j++){
        int_vector.Add(OrderTicket());
     }
int_matrix.Add(int_vector);
}

int_matrix.Delete(0);            //// DOESN'T WORK
----------------------------------------------------------

Thanks a lot,

Kind Regards,
Abel
