evaluate an Algebraic expression

 

Calling Sequence

Description

Examples

Calling Sequence

Algebraic eval() throws MapleException

Description

• 

The eval function evaluates the Maple expression represented by the current Algebraic object and returns the result as a new Algebraic.

• 

The current Algebraic object is unchanged by this call.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

    public static void main( String notused[] ) throws MapleException

    {

        String mapleArgs[];

        Engine engine;

        Algebraic a1, a2;

        mapleArgs = new String[1];

        mapleArgs[0] = "java";

        engine = new Engine( mapleArgs, new EngineCallBacksDefault(),

                null, null );

        a1 = engine.evaluate( "''int''(x,x):" );

        a2 = a1.eval( );

        System.out.println( "a1 = "+a1 );

        System.out.println( "a2 = "+a2 );

    }

}

Executing this code should produce the following output.

a1 = int(x,x)

a2 = 1/2*x^2
