autoplot=0 is the default value. |
|
If it is 1, then this function outputs an input for plot |
|
(which is equivalent to setting the 3rd argument of the mode parameter properly). |
|
When ans is the output, ans[1,] is c(q,prob at q,...), ans[2,] is c(q0,prob at q0,...), and ans[3,] is c(q0+q/100,prob at q/100,...), ... |
|
When the adaptive Runge-Kutta method is used, the step size h may change |
|
automatically, |
|
which makes the sampling period change, in other words, the sampling points |
|
q0+q/100, q0+2*q/100, q0+3*q/100, ... may change. |
|
In this case, the output matrix may contain zero rows in the tail or overfull. |
|
In case of the overful, use the mode option to get the all result. |
