Plotting data from simulink using to workspace block and getting error in code.

below is an excerpt of the relevant code and the corresponding SIMULINK block diagram. I have provided the out.simX information including variable name below. The out.simU block follows the same structure. I am using version 2020b.

t = simX.Time;
u1 = simU.Data(:,1);
u2 = simU.Data(:,2);
u3 = simU.Data(:,3);
u4 = simU.Data(:,4);
u5 = simU.Data(:,5);
x1 = simX.Data(:,1)

在 MATLAB Online 中打开

 t = ans.simX.Time;
 
  u1 = ans.simU.Data(:,1);
  u2 = ans.simU.Data(:,2);
  u3 = ans.simU.Data(:,3);
  u4 = ans.simU.Data(:,4);
  u5 = ans.simU.Data(:,5);
 
  x1 = ans.simX.Data(:,1);
  x2 = ans.simX.Data(:,2);
  x3 = ans.simX.Data(:,3);
  x4 = ans.simX.Data(:,4);
  x5 = ans.simX.Data(:,5);
  x6 = ans.simX.Data(:,6);

Solved the issue for anyone who may be having the same trouble. After running the model it is saved as ans in the workbench so i modified the code accordingly. Probably a novice mistake but I am told the code has changed in the previous version or two so the tutorial I was following had me stumped. Anyhow, it works.
