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 $i-1$.
 • 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 = { "java" }; Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null ); AlgebraicRTable a1 = (AlgebraicRTable)engine.evaluate( "Array( 1..2, 1..2, [[a,b],[c,d]]):" ); int[] index = new int; Algebraic e = engine.evaluate("w:"); index = 1; index = 1; a1.assign( index, e ); e = engine.evaluate("x:"); index = 2; index = 1; a1.assign( index, e ); e = engine.evaluate("y:"); index = 1; index = 2; a1.assign( index, e ); e = engine.evaluate("z:"); index = 2; index = 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)
