Scilab: The open source platform for numerical computation

project page: http://www.scilab.org/
code syntax: http://www.scilab.org/product/man/

Wrapping

input: ”.sci” script file
input parameters syntax
- variable:
```
#(variable_name)
```
- formula:
```
@<formula_expression>
```
output: detects output expressions like
```
disp(“z =”+string(...))
```
lower case output taken as scalar float, upper case as 1D array of float
running progress: last line of output stream

Example

input file:

x1=#x1 * 15-5;
x2=#x2 * 15;
 
X=[x1,x2]
 
disp("X = "+string(X(1))+string(X(2));
disp("z = "+string((x2 - 5/(4*%pi^2)*(x1^2) + 5/%pi*x1 - 6)^2 + 10*(1 - 1/(8*%pi))*cos(x1) + 10));
 
exit

input variables: x1, x2
output: z (scalar), X (array)

Installation

user side:
- unzip
  plugin-Scilab.zip
  in Promethee installation directory,
- restart Promethee GUI.
server side:
- unzip
  plugin-Scilab.zip
  in Promethee installation directory,
- open shell console, check “scilab -nw -f Promethee_Install_Path/examples/0d_Scilab.sci” returns numerical values,
- add
```
 <CODE name="Scilab" cplugin="file:./plugins/calc/Scilab.cplugin.jar" command="scilab -nw -f" />
```
  line in calculator.xml file inside ”<calculator>” tag,
- wait for configuration refresh (5 s. if calculator is free).
