ComplexNumericRTable.assign

assign a complex double into a ComplexNumericRTable

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

Parameters

 index - the index of the entry to assign val - the ComplexNumeric

Description

 • The assign function assigns the ComplexNumeric val into the element of the ComplexNumericRTable indexed by index.
 • The index parameter is an array of integers, one for each dimension of the ComplexNumericRTable. 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 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; ComplexNumericRTable cnRt; ComplexNumeric cn; int index[]; mapleArgs = new String[1]; mapleArgs[0] = "java"; engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null ); cnRt = (ComplexNumericRTable)engine.evaluate( "Array( 1..2, 1..2, [[1+I, 2+2*I],[3+3*I, 4+4*I]], datatype=complex(sfloat) ):" ); index = new int[2]; index[0] = 1; index[1] = 1; cn = (ComplexNumeric)engine.evaluate( "10+5*I:" ); cnRt.assign( index, cn ); index[0] = 1; index[1] = 2; cn = (ComplexNumeric)engine.evaluate( "20+10*I:" ); cnRt.assign( index, cn ); index[0] = 2; index[1] = 1; cn = (ComplexNumeric)engine.evaluate( "30+15*I:" ); cnRt.assign( index, cn ); index[0] = 2; index[1] = 2; cn = (ComplexNumeric)engine.evaluate( "40+20*I:" ); cnRt.assign( index, cn ); System.out.println( cnRt ); } }

Executing this code produces the following output.

 Array(1..2, 1..2, [[10.+5.*I,20.+10.*I],[30.+15.*I,40.+20.*I]], datatype = complex(sfloat), storage = rectangular, order = Fortran_order)
