|
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.

class Example

System.out.println( p.execute() );
|
System.out.println( p.executehf() );
|
p = (Procedure)engine.evaluate( "proc( x,y,z ) return (x+y)/z; end proc:" );
|
args = new Algebraic[3];
|
args[0] = engine.newNumeric( 100 );
|
args[1] = engine.newNumeric( 900 );
|
args[2] = engine.newNumeric( 15 );
|
System.out.println( p.execute( args ) );
|
p = (Procedure)engine.evaluate( "proc( x ) return sin(Pi*x); end proc:" );
|
e = engine.newExpseq( 1 );
|
e.assign( 1, engine.newNumeric( 1000 ) );
|
e = (Expseq)e.unique();
|
System.out.println( p.execute( args ) );
|
}
