| Shenghui, you make a good suggestion, but I believe the 3 point formula is better implemented as: ListConvolve[{1, 0, -1}, data[[All, 2]]] / ListConvolve[{1, 0, -1}, data[[All, 1]]] |
| Yes, it is possible. As soon as you have an equation we might be in the position to help you further. Have fun! |
| Dear Marco, Thanks a lot for your explanations! Yes, it works. Thanks again for your help. Btw, may I ask you another thing? I have a PDF of normal distribution of a certain variable, like in this case, the value of a (please refer to below... |
| Are you able to run the NDSolve using exactly the information shown in this thread? I cannot. |
| Dear Ivan, Thanks for your response. I really appreciate it. Yes, you are right. It has something to do with the usage of lists. So I changed my equation into: sol = NDSolve[{q'[t] == (a q[t]^b newefr[t] - q[t]) + (a q[t]^b (newefr[t] -... |
| Dear All, I want to ask your advice about clustering method. I have rock type data for 22 catchments and the data consists of the area of each rock type in terms of percentage and also in km^2 (please refer to the excel sheet as per attached). By... |
| Dear Daniel, Thanks for your comments. There is a physical meaning for using only small range data set so that's the reason why I am trying not to use the full range data set, if possible. However, thanks a lot for your comments. I am considering... |
| Hi Marco, It seems like someone ever discussed about it before [http://mathematica.stackexchange.com/questions/28186/can-mathematica-9-peacefully-coexist-with-mathematica-8-on-windows ] and it's said there is no problem to install multiple versions... |
| Dear Daniel and Bill, Thanks a lot for your explanations. It's really helpful. Thanks and Regards, Intan |
