Scope can easily shown you the result of the simuilation. However, it is not clear when the graph from the scope is transfer to the Word document. Here is the step to properly plot graph from Simulink simulation.<\/p>\n

  1. Add “To workspace” block into the simulation. [Library>Simulink>Sinks>To Workspace]
    \n\"\"<\/li>\n
  2. Change the variable name according to your specification. Change the “Save format” to “Array”.
    \n\"\"<\/li>\n
  3. Add “Clock” block into the simulation to record the time. [Library>Simulink>Sources>Clock]
    \n\"\"<\/li>\n
  4. Copy the “To workspace” block to the signal you want to plot. Connect the “Clock” to the “To workspace” block.
    \n\"\"<\/li>\n
  5. Run the simulation. All the signals connected to the “To workspace” are now available in the MATLAB Workspace area.

  6. Open a new script in MATLAB.

  8. The figure produced by the script is better compared to the scope.
    \n\"\"<\/li>\n
  9. To transfer the figure to the Word document, adjust the figure to the desired size. Then “Edit”>”Copy Figure”. Paste to Word document.
