Question

function [Li_current] = light_influent [SimulationTime] 
switch flag_light 
     case 0 
      %Light intensity is set to a constant value for the whole simulation 
      Li_current= pKt.Li 
     case 1 
      %Light intensity periodically alternates between 'on' at a set value or 'off' 
      get_param (MyModel, SimulationTime) 

Answer 1

ここでは、永続変数を使用するのが基本です。ライトがオンかオフかに関係なく、毎秒ライトのオンとオフを切り替える最小の実例があります。

function [Li_current] = light_influent(SimulationTime) 

% Declare and initialize the persistent variable during the first run 
persistent lastTime 
persistent lightOn 
if isempty(lastTime) 
    lastTime = SimulationTime; 
end 
if isempty(lightOn) 
    % Start with the light off 
    lightOn = false; 
end 
disp([ lastTime, SimulationTime, lightOn ]) 

% Declared here for testing purposes... 
flag_light = 1; 
switch flag_light 
case 0 
    %Light intensity is set to a constant value for the whole simulation 
    Li_current = 1; 
case 1 
    %Light intensity periodically alternates between 'on' at a set value or 'off' 
    % Switch every one second. 
    switchFrequency = 1; 
    if (SimulationTime - lastTime) > switchFrequency 
     % If the light is on, turn it off. If off, turn it on 
     lightOn = ~lightOn; 
     lastTime = SimulationTime; 
     disp('switched') 
    end 
    if lightOn 
     Li_current = 1; 
    else 
     Li_current = 0; 
    end 
end
