Description
Examples
Algebraic select( int index[] ) throws MapleException
index
-
index of the entry to select
The select function returns the Algebraic object indexed by index in the AlgebraicRTable.
index 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.
