javasci

Call Scilab engine from a Java application

Description

Scilab offers the possibility to be called from a Java application.

This help describes the features of the javasci API.

Since Scilab version 5.3.0, a new version of Javasci called Javasci v2 has been introduced. This version fixes most of the limitations of Javasci v1.

Browse the documentation of Javasci v2. (this will open the web browser).

Example of Javasci v2

// A simple Java example with javasci v2
// Filename: DisplayPI.java

import org.scilab.modules.javasci.Scilab;
import org.scilab.modules.types.ScilabType;
import org.scilab.modules.types.ScilabDouble;

class Example1 {

    public static void main(String[] args) {

      try {
            Scilab sci = new Scilab();
            sci.open();
            sci.exec("disp(%pi);");

            ScilabDouble a = new ScilabDouble(3.14);
            sci.put("a",a);
            sci.exec("b=sin(a);");
            ScilabType b = sci.get("b");
            System.out.println("b = " + b);

            sci.close();

      } catch (org.scilab.modules.javasci.JavasciException e) {
            System.err.println("An exception occurred: " + e.getLocalizedMessage());
      }

    }
}

Here is an other easy example:

------ Example1.java ------
import org.scilab.modules.javasci.Scilab;
import org.scilab.modules.types.ScilabType;
import org.scilab.modules.types.ScilabDouble;

class Example1 {

public static void main(String[] args) {

try {
Scilab sci = new Scilab();
sci.open();
sci.exec("disp(%pi);");

double [][]data={{42, Math.PI}};
ScilabDouble a = new ScilabDouble(data);
sci.put("a",a);
sci.exec("b=cos(a);");
ScilabType b = sci.get("b");
System.out.println("b = " + b);

sci.close();

} catch (org.scilab.modules.javasci.JavasciException e) {
System.err.println("An exception occurred: " + e.getLocalizedMessage());
}

}
}

I receive an error in running this
Exception in thread "main"
java.lang.UnsatisfiedLinkError:
org.scilab.modules.javasci.Call_ScilabJNI.getDouble(Ljava/lang/String;)[[D

I suppose that that is because my jar files are old (I downloaded them from other websites)
how can I download the two important jar files from your website?
More I searched, less I found.

The problem (lack of jar files) was solved.
After installation of the newer version of the scilab (5.5.0), you can find them in your program files, if you are a windows user
