GainStruct can be used to set gains of groups
The struct created by this function can be used to set a variety of
gains on a group of modules. Please consult the online
documentation to find out more about the individual gain settings.
NaNs for any values in gains or control parmaters are ignored. In
these cases any existing setting on the module for that parameter
will remain unmodified.
% Set the control strategy of a 2 module group to strategy 4
gains = GainStruct()
gains.controlStrategy = [4 4];
