-====== Calc Transition Matrix Using Vensim ====== ​ 
- 
-===== Description ===== 
- 
-Gets transition rates from variables specified in a Vensim external model. ​ 
- 
-===== Inputs ===== 
- 
-^ Name ^ Type ^ Description ^ 
-| Landscape ​ | [[ Categorical Map Type| Categorical Map  ]]  | Map of classes or categories. ​  | 
-| Vensim Model Filename ​ | [[Path Type|Path ​ ]] |  Vensim model filename and path.  | 
-| Initial Area Variables ​ | [[Vensim Category Variable Set Type|Vensim Category Variable Set  ]]  | List of Vensim variables selected to receive the initial land use and cover area distribution. The area figures are transferred to Vensim in hectares. ​ | 
-| Transition Rate Variables ​ | [[Vensim Transition Variable Matrix Type|Vensim Transition Variable Matrix ​ ]] | Matrix of Vensim variables that output the transition rates to be passed to Dinamica. ​ | 
-| Initial Time  | [[Non Negative Int Type|Non Negative Int  ]]  | Simulation initial time according to Vensim time specification. ​ | 
- 
-===== Optional Inputs ===== 
- 
-^ Name ^ Type ^ Description ^ Default Value ^ 
-| Step  | [[ Non Negative Int Type| Non Negative Int  ]]  | Current step or model iteration. ​ | 0  | 
- 
-===== Outputs ===== 
- 
-^ Name ^ Type ^ Description ^ 
-| Transition Matrix ​ | [[ Transition Matrix Type| Transition Matrix ​ ]]  | Matrix of transition rates. ​ | 
- 
-===== Group ===== 
- 
-[[Functor List#​Simulation | Simulation]] 
- 
-===== Notes =====  
- 
-A linkage between [[http://​www.vensim.com | Vensim]] - a system thinking software - and Dinamica EGO was developed. A complex model can be written by using this software and its results passed simultaneously to Dinamica EGO. As a result both models can be coupled by the exchange of dynamic transition rates and the distribution of land use and land cover classes.
