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 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  is stored in the array at position  .
|
|
•
|
As AlgebraicRTables do not have unique representations, elements of an AlgebraicRTable can be assigned to at any time.

|
|
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)
