Allan CORNET & Sylvestre LEDRUScilab Consortium


Interaction to make Scilab the reference in numerical computation

● In interacting with new application fields,

● In acquiring new functionalities,

● In facilitating the communication, exchange and collaboration with other software,

● In integrating the results of the most recent scientific breakthroughs in the field of numerical computation.


Key Advantages

● For Scilab Users:

– No need to learn another software,

– Adapt and use the software according to their needs,

– Develop exchanges and facilitate collaboration among different users communities.

● For Scilab Software:

– Give access to Scilab features from another software and vice versa,

– Add functionalities to Scilab in several areas,

– Enhance the scope of use of Scilab.

Scilab and Excel® Excel is a trademark of Microsoft Corporation


Control Excel® from Scilab

• xls_link: http://atoms.scilab.org/toolboxes/xls_link

• Take the control of Excel® from Scilab:• // Call a new instance of Excel• r = xls_NewExcel();• // Create a Workbook• xls_AddWorkbook();• // Set Worksheet 1 (visible on)• xls_SetWorksheet(1);• // set visible excel windows• xls_SetVisible(%t);• // send data to excel• xls_SetData("A2", eye(10,10))• // get data from excel• M = xls_GetData(xls_CalculateRange("A2",[10,10]))

OLE/COM Client for Scilab (beta)

• Automation module for Scilab:

http://forge.scilab.org/index.php/p/ole

• Provide a Component Object Model Client to call and interoperate with code written in any other language (COM aware)

• COM is one of the main ways to glue applications and components together on Windows platforms.

OLE/COM Client for Scilab (beta)

Example

We call VBScript from Scilab :

• pScript = ole_actxserver('MSScriptControl.ScriptControl')

• ole_set(pScript, 'Language', 'VBScript')

• ole_invoke(pScript,'Eval','MsgBox(""Hello world"")') ;

• ole_invoke(pScript,'Eval','68 + 1')

• ole_delete(pScript)

How to make interaction possible?



call_scilab: Scilab as a computing engine

• Access to Scilab features from native code (ie thirdparty application)

• C or C++ API. Similar syntax to api_scilab

• Send and retrieve Scilab variables to/from Scilab

ScilabEngine

Call_Scilab Application


call_scilab: Example

0001 /* 0002 * Write a matrix into Scilab0003 * B=[1 4 2 3; 0004 * 3 9 8 2 ]0005 * Note that it is done column by column0006 */ 0007 double B[] = { 1,3,4,9,2,8,3,2} ; /* Declare the matrix */

0008 int rowB = 2, colB = 4; /* Size of the matrix */0009 char variableNameB[] = ”B”;0010 0011 /*0012 * Write it into Scilab’s memory 0013 */0014 createNamedMatrixOfDouble(pvApiCtx,variableNameB,rowB,colB, B);0015 0016 printf(”Display from Scilab of B:\ n”);0017 SendScilabJob(”disp(B);”); /* Display B *

Display from Scilab of B: 1. 4. 2. 3. 3. 9. 8. 2.

C code: Final output:


javasci: Scilab as a computing engine for Java

• Access to Scilab features from Java

• Based on call_scilab

• New version introduced in Scilab 5.3.0

• Provide mapping of Scilab variables in Java

• Send and retrieve Scilab variables to/from Scilab

– Access third-party java classes,

– Pass data between Scilab variables and Java objects.

Available through ATOMS: http://atoms.scilab.org/toolboxes/JIMS or atomsInstall('JIMS')

example :jimport java.lang.String

s = String.new('hello')

jimport java.util.Enumeration

jgetmethods(Enumeration)

http://atoms.scilab.org/toolboxes/JIMS


And

● dNIMS: GSOC 2011

Ability for calling .NET framework or Mono from Scilab.
