# Template:Index-matrix

This template is not to be used alone. Please use:

 this scheme if you draw IM of predicates {{index-matrix/start}} {{index-matrix/row-predic}} ... {{index-matrix/row-predic}} {{index-matrix/end}}  OR this scheme if you draw IM of arc capacities {{index-matrix/start}} {{index-matrix/row-arccap}} ... {{index-matrix/row-arccap}} {{index-matrix/end}} 

The column definitions go in index-matrix/start : Please define N (number of columns) and insert as many parameters as necessary.

{{index-matrix/start
|matrix-id =
|columns = N
|1 =
|2 =
...
|N-1 =
|N =
}}


Maximal number of columns is 10. New columns can be easily added in template:index-matrix/start, template:index-matrix/row-predic and template:index-matrix/row-arccap.

Every separate row goes in index-matrix/row-predic or index-matrix/row-arccap (all rows in table have to be from the same kind):

 {{index-matrix/row-predic |columns= N |row-id = |1 = |2 = ... |N-1 = |N = }}  OR {{index-matrix/row-arccap |columns= N |row-id = |1 = |2 = ... |N-1 = |N = }} 

The difference comes from the default values for blank parameter 1,...,N. Leave it blank after the = sign and it will produce (on screen, but not in the source code) false for the /row-predic and 0 for the /row-arccap. Repeat as many times, as number of rows in your index matrix. Do not forget to finish with

{{index-matrix/end}}


## Example

### Predicate

{{index-matrix/start
|matrix-id = IM<sub>P</sub>
|columns = 2
|1 = column<sup>1</sup>
|2 = column<sup>2</sup>
}}
{{index-matrix/row-predic
|columns= 2
|row-id = row<sub>1</sub>
|1 =
|2 = cell<sub>1</sub><sup>2</sup>
}}
{{index-matrix/row-predic
|columns= 2
|row-id = row<sub>2</sub>
|1 = cell<sub>2</sub><sup>1</sup>
|2 = cell<sub>2</sub><sup>2</sup>
}}
{{index-matrix/end}}

 IMP =
 column1 column2 row1 false cell12 row2 cell21 cell22

### Arccapacity

{{index-matrix/start
|matrix-id = IM<sub>AC</sub>
|columns = 2
|1 = column<sup>1</sup>
|2 = column<sup>2</sup>
}}
{{index-matrix/row-arccap
|columns= 2
|row-id = row<sub>1</sub>
|1 =
|2 = cell<sub>1</sub><sup>2</sup>
}}
{{index-matrix/row-arccap
|columns= 2
|row-id = row<sub>2</sub>
|1 = cell<sub>2</sub><sup>1</sup>
|2 = cell<sub>2</sub><sup>2</sup>
}}
{{index-matrix/end}}

 IMAC =
 column1 column2 row1 0 cell12 row2 cell21 cell22

## Alternative

If you have ready index matrix in LaTeX, you can use it immediately; you only have to place the code between  in order to make the LaTeX engine recognize the source code. Note that here you cannot leave parameters blank and expect them to obtain null value (0 or false).

$r = \begin{array}{c|c c} & column^{1} & column^{2} \\ \hline row_{1} & cell_{1}^{1} & cell_{1}^{2}\\ row_{2} & cell_{2}^{1} & cell_{2}^{2}\\ \end{array}$

$\displaystyle{ r = \begin{array}{c|c c} & column^{1} & column^{2} \\ \hline row_{1} & cell_{1}^{1} & cell_{1}^{2}\\ row_{2} & cell_{2}^{1} & cell_{2}^{2}\\ \end{array} }$
