struct forcefields::Ccl::Rho¶

Overview¶

\(\rho\) parameter in paper. More…

#include <ccl.hpp>
 
struct Rho {
    // fields
 
    double _1;
    double _2;
    double _3;
    double n[3];
};

\(\rho\) parameter in paper.

double _1

rho^1

double _2

rho^2

double _3

rho^3

double n[3]

Convert derivative to force. Vector n is by definition the vector which satisfy the equation:

\[\mathbf{F}=-\frac{dE}{d\rho}\mathbf{n}\]

It is equal to:

\[\mathbf n=\frac{\mathbf{r}}{|\mathbf{r}|}\frac{r_e}{\rho^2}\]
