float select( int index[] ) throws MapleException
index
-
index of the entry to select
The select function returns the Java float indexed by index in the FloatRTable
The index function is an array of integers, one for each dimension of the FloatRTable. 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.

DoubleRTable rt = (DoubleRTable)engine.evaluate( "Array( 1..2, 1..2, evalf( [[1/3, 1/4],[1/5,1/6]] ), datatype=float[8] ):" );
int[] index = new int[2];
index[0] = 1;
index[1] = 1;

System.out.println( d );
index[1] = 2;
d = rt.select( index );
