Hi guys, I recently started using ginac, and one thing I couldnt figure out from the tutorial is how can I make an expression one piece at a time. So if I wanted to build an expresison out of a list like x,=,5,*,4<br><br>I imagine doing something like <br>ex expr;<br>expr.append(x);<br>expr.append(==);<br>expr.append(5);<br>expr.append(4);<br><br>I understand the numbers are numerics, and x would be a symbol, but I dont know what the operators would be ( * / + - ).<br><br>Does anyone how I can do this? Does this even make any sense to you? Thanks for any replies!<br><br>R. Gordon<br> </div></body>
