Parameters

Description

Examples

Calling Sequence

Expseq newExpseq( int length ) throws MapleException

Parameters

length

-

length of the expression sequence to be returned

Description

• 

The newExpseq method creates a new Maple expression sequence of length length.  The expression sequence is represented with a Expseq object.

• 

The elements of the expression sequence must be initialized and the unique member function must be called before it can be passed into a Java Open Maple function.

• 

Errors that occur within the Maple session are reported via errorCallBack, other errors are raised as a MapleException.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

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

    {

        String[] mapleArgs = { "java" };

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

        Expseq e = (Expseq)engine.newExpseq( 3 );

        e.assign( 1, engine.newNumeric( 12345 ) );

        e.assign( 2, engine.newNumeric( 1.8 ) );

        e.assign( 3, engine.newNumeric( 1./3 ) );

        e = (Expseq)e.unique();

        System.out.println( e );

    }

}

Executing this code produces the following output.

[12345, 1.70000000000000004, .333333333333333315]
