Computation units
[this page | pdf | references]
Currently, the number of computation units deducted from your Session Id when you run
PrincipalComponentsSizes (i.e. MnPrincipalComponentsSizes) is
(a) programmatically: the following number or derived using the following formula: Max(1,m*m*Max(m, n)/1000).
(b) interactively: 30 less than (a), subject to a minimum of zero. If the units deducted exceed zero then you will need a
SessionId to complete the calculation.
