MODIFYTIMESTEP modifies the timestep of a ssm object %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: MODIFYTIMESTEP modifies the timestep of a ssm object, and updates the A and B matrices supposing there is no aliasing. CALL: sys = modifyTimeStep(sys,pl) INPUTS: sys - (array of) ssm objects pl - A plist or numeric value giving new timestep value (param name 'newtimestep') OUTPUTS: sys - (array of) ssm Parameters Description %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
