How are the coverage metrics for the Delta column computed in a Cumulative coverage report in Simulink Verification and Validation 2.5 (R2009a)?

I would like to know how the coverage metrics for the Delta column computed in a Cumulative coverage report.

This change has been incorporated into the documentation in Release 2010a (R2010a). For previous releases, read below for any additional information:

The delta column in a cumulative coverage report is arrived as follows:

delta_d = (d_n+1>0 & d_n ==0).*d_n+1

where

d_n+1 is the coverage data at the end of the current (n+1)th iteration

d_n is the coverage data at the end of the nth iteration

That is the delta column will show non-zero change only when d_n is zero.
