AlgebraicRTable.assign - assign an Algebraic into an AlgebraicRTable

Calling Sequence

void assign( int index[], Algebraic val ) throws MapleException

Parameters

index

-

index of the entry to assign

val

-

value to assign into the list

Description

• 

The assign function assigns the Algebraic object val into the element of the AlgebraicRTable indexed by index.

• 

The index parameter is an array of integers, one for each dimension of the AlgebraicRTable.  Each integer must be within the bounds determined by lowerBound and upperBound.  The index for dimension i is stored in the array at position i1.

• 

As AlgebraicRTables do not have unique representations, elements of an AlgebraicRTable can be assigned to at any time.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

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

    {

    String mapleArgs[];

    Engine engine;

    AlgebraicRTable a1;

    Algebraic e;

    int index[];

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    a1 = (AlgebraicRTable)engine.evaluate( "Array( 1..2, 1..2, [[a,b],[c,d]]):" );

    index = new int[2];

    e = engine.evaluate("w:");

    index[0] = 1;

    index[1] = 1;

    a1.assign( index, e );

    e = engine.evaluate("x:");

    index[0] = 2;

    index[1] = 1;

    a1.assign( index, e );

    e = engine.evaluate("y:");

    index[0] = 1;

    index[1] = 2;

    a1.assign( index, e );

    e = engine.evaluate("z:");

    index[0] = 2;

    index[1] = 2;

    a1.assign( index, e );

    System.out.println( a1 );

    }

}

Executing this code produces the following output.

Array(1..2, 1..2, [[w,y],[x,z]], datatype = anything, storage = rectangular,

order = Fortran_order)
