====== Symbol ======

In mathematical expressions it is common to use symbols for variables and parameters. Ecolego uses (by default) symbols in the [[Report_window|reports window]] and the [[Information_window|information window]] to keep the expressions short and as close to pure mathematical notation as possible.

You can choose either assign a symbol explicitly, or to let Ecolego “create” a symbol for your object.

A symbol in Ecolego is composed of a center symbol and (potential) notations in each corner:

|Top left   |      |Top right   |
|           |Center|            |
|Bottom left|      |Bottom right|

For example:

||   |i,j|
||DCC|   |
||   |k  |

The window which appears when clicking a **Symbol** button will list the most common tokens used for symbols, like the Greek and Hebrew alphabet.

==== Automatic symbols ====

When no symbol is assigned to an object, Ecolego will use the name of the object to automatically generate a symbol. If names of greek letters appear in the name, such as in “Alpha” and “k_beta”, these will be replaced with actual greek letters. The first underscore will be used as a sub notation and every subsequent underscore will be written as a comma (’,’). For example:

^Name        ^Symbol              ^
|Kd_soil     |Kd<sub>soil</sub>   |
|rho_soil_dry|ρ<sub>soil,dry</sub>|
|Lambda_0    |Λ<sub>0</sub>       |
