NumericRTable.assign

assign a Numeric into an element of the NumericRTable

 Calling Sequence void assign( int index[], Numeric val ) throws MapleException

Parameters

 index - index of the entry to assign val - value to assign to the list

Description

 • The assign function assigns the Java Numeric val into the element of the NumericRTable indexed by index.
 • The index parameter is an array of integers, one for each dimension of the NumericRTable.  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 RTables do not have unique representations, elements of an RTable can be assigned to 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; NumericRTable a1; int index[]; Numeric n; mapleArgs = new String[1]; mapleArgs[0] = "java"; engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null ); a1 = (NumericRTable)engine.evaluate( "Array( 1..2, 1..2,[[3^60,3^61],[3^62,3^63]], datatype=sfloat):" ); index = new int[2]; n = (Numeric)engine.evaluate( "4^60:" ); index[0] = 1; index[1] = 1; a1.assign( index, n ); n = (Numeric)engine.evaluate( "4^61:" ); index[0] = 2; index[1] = 1; a1.assign( index, n ); n = (Numeric)engine.evaluate( "4^62:" ); index[0] = 1; index[1] = 2; a1.assign( index, n ); n = (Numeric)engine.evaluate( "4^63:" ); index[0] = 2; index[1] = 2; a1.assign( index, n ); System.out.println( a1 ); } }

Executing this code produces the following output.

 Array(1..2, 1..2, [[.1329227996e37,.2126764793e38],[.5316911983e37,.8507059173e38]], datatype = sfloat, storage = rectangular, order = Fortran_order)
