Specify frequency to log stochastic simulation output
LogDecimation is a property of the SolverOptions property,
which is a property of a configset object. This
property defines how often stochastic simulation data is recorded. LogDecimation is
available only for stochastic solvers (ssa, expltau,
and impltau).
Use LogDecimation to specify how frequently
you want to record the output of the simulation. For example, if you
set LogDecimation to 1, for
the command [t,x] = sbiosimulate(modelObj), at
each simulation step the time will be logged in t and
the quantity of each logged species will be logged as a row in x.
If LogDecimation is 10, then
every 10th simulation step will be logged in t and x.

This example shows how to change LogDecimation settings.
Retrieve the configset object from
the modelObj, and change the SolverType to expltau.
modelObj = sbiomodel('cell'); configsetObj = getconfigset(modelObj); set(configsetObj, 'SolverType', 'expltau')
Change the LogDecimation to 10.
set(configsetObj.SolverOptions, 'LogDecimation', 10); get(configsetObj.SolverOptions, 'LogDecimation') ans = 10
