Help with workspace data extraction shortcut

1 次查看(过去 30 天)
I am trying to extract data from the workspace from various possible locations.
X.output.name.param1(:,end)
X.output.name.param2(:,end)
:
X.output.name.paramN(:,end)
If possible, I would like to try access it via a named parameter, like below.
line 1: param = 'param2';
line 2: y = X.output.name.(param);
Doing this partly appears to work. I can see my data as a 25x3 matrix.
But how do i home in on the 3rd 'end' column by editing line 2, and not line 1?
Regards, Dave

Hi Dave,
  1. From Workspace Block:
  • Use the From Workspace block in your Simulink model. This block reads data from a workspace and provides it as a signal or a nonvirtual bus at the block’s output1.
  • To read more about "From Workspace" block, click the link below - https://www.mathworks.com/help/simulink/slref/fromworkspace.html
  • Specify the data you want to load using the Data parameter. You can use a MATLAB expression (e.g., a variable name) that evaluates to data in a format supported by the block.
  • Connect the output of the From Workspace block to your desired location in your model.
2. Accessing Logged Data:
  • If you’re logging data using a To Workspace block, you can access the logged data using the variable name specified in the Variable name parameter of the block2.
  • Use a dot notation with the variable name to access specific columns or elements.For example:
% Assuming 'simout' contains your logged data
y = simout.param2(:, end); % Access the 3rd 'end' column
3. Model Workspace
Hope this helps!
