Hello, Over the course of an entire year, I would like to run the
system model I have developed selectively; between the hours of 7 p.m. and 8
a.m. the following day, six days a week, always starting with the same initial
conditions. Essentially, I would like to ignore the period between 8 a.m.
and 7.pm., not making any calculations during that time period and start with
the same initial conditions every day at 7 p.m. Does anyone have experience
with a similar calculation or any ideas as to how I might go about this? Thank you for your time, Ethan Lust University of Maryland |
