% MCOMPARE : MCOMPARE ( [ 'file1' ; 'file2' ] , [ 'var1' ; 'var2' ...] )
|
|
% This optional command plots the relative differences between
|
|
% two different simulations for a list of variables. One plot
|
|
% is drawn for each variable. The trajectories must have been
|
|
% previously saved by the instruction DYNASAVE. The simulation
|
|
% in file1 serves as the base simulation and the ploted quantity
|
|
% is equal to the difference between the two simulation reported
|
|
% to the first one. If, for a given variable, zero is one of the
|
|
% value of the base simulation, the absolute difference is ploted
|
|
% instead of the relative one.
