void assign( int index[], double val ) throws MapleException
|
|
|
Parameters

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

Description
|
|
|
•
|
The assign function assigns the Java double val into the element of the DoubleRTable indexed by index.
|
|
•
|
The index parameter is an array of integers, one for each dimension of the DoubleRTable. Each integer must be within the bounds determined by lowerBound and upperBound. The index for dimension  is stored in the array at position  .
|
|
•
|
As RTables do not have unique representations, elements of an RTable can be assigned to at any time.

|
|
index[0] = 2;
|
|
index[1] = 1;
|
|
rt.assign( index, 2./5 );
|
|
index[0] = 2;
|
|

|
|
rt.assign( index, 2./6 );
