Divide a scalar by a vector

Fri Feb 01, 2019 2:23 pm
I wanted to assign a vector with a scalar divided by a vector.
How could be done?

Code: Select all
VectorXd w;
... // w initialization
VectorXd T = 2/w; // This is not directly possible. How to do it?

Probably you should multiply the vector by the inverse of the scalar:

Code: Select all
VectorXd w;
... // w initialization
VectorXd T = w * (1 / 2);
