 execute - Maple Help

Procedure.execute

execute a Maple procedure Calling Sequence Algebraic execute( ) throws MapleException Algebraic execute( Expseq eArgs ) throws MapleException Algebraic execute( Algebraic aArgs[] ) throws MapleException Parameters

 eArgs - expression sequence of arguments to the procedure aArgs - array of Algebraic objects to be used as arguments to the procedure Description

 • The execute function executes the procedure represented by the Procedure object with the given arguments.
 • The result of the procedure call is returned as an Algebraic object. 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 ); Procedure p = (Procedure)engine.evaluate( "proc( ) return Pi; end proc:" ); System.out.println( p.execute() ); System.out.println( p.executehf() ); p = (Procedure)engine.evaluate( "proc( x,y,z ) return (x+y)/z; end proc:" ); Algebraic[] args = new Algebraic; args = engine.newNumeric( 100 ); args = engine.newNumeric( 900 ); args = engine.newNumeric( 15 ); System.out.println( p.execute( args ) ); p = (Procedure)engine.evaluate( "proc( x ) return sin(Pi*x); end proc:" ); Expseq e = engine.newExpseq( 1 ); e.assign( 1, engine.newNumeric( 1000 ) ); e = (Expseq)e.unique(); System.out.println( p.execute( args ) ); } }

Executing this code produces the following output.

 Pi 3.141592653589793 200/3 0
