2016-01-28 13:14:29 +0100 | commented answer | How to define finite difference approximation for first order derivative $y_{k+1} $ and $y_k$ needs to remain unknown till the formation of equation, so that they can act as variables in the linear system. My interest is to automate the finite difference method in sage. Should I need to define some new data structure. Thanks for responding though!!! |

2016-01-26 02:59:11 +0100 | asked a question | How to define finite difference approximation for first order derivative I need to define $$y1(k)=\frac{y_{k+1}-y_{k-1}}{2*h}$$ in sage so that sage can differ between symbolic $$y_{k+1}$$ and $$y_{k}$$. Would somebody please help? |
