I see a possible problem here. The result from running ORTH should not be two separate values on the stack as you apparently show like this: Level 2: 0.008 Level 1: 672.345 The result should be a 2 row, 1 column matrix like this: [[ 0.008 ] [ 672.345 ]] So, which is the ORTH result, two values or a matrix?
