I&#39;d like to be able to write things like<br><br>a = b + f(c)<br><br>where <br>a is a vector (or matrix) <br>b, c are vector (or matrix) expressions<br>f is a function to be applied to every element in c<br><br>What do I need to do in order to get my function application behave as an ublas (vector or matrix) expression?<br>
<br>The objective is to integrate it into the expression template of ublas in order to avoid temporaries.<br><br>TIA<br><br>
