A basic guide tht will (Hopefully) make it easier to use plots in Matlab

TL;DR

• Use the to file block in simulink to get data to a .mat file
• load('filename') loads the data from a .mat file to the matlab workspace
• print('filename', '-depsc') saves the plot that is currntly displayed as in eps-format with colours

Running the guide

Open guide.m in the top folder

1. Run the entire script first (Or just run the init-section)
2. Find a plot that has something you need
3. The section corresponding to (ctrl+f) to find the section ( It has the same name as the title of the plot)
4. To only run one section hit (ctrl+enter)
   • The current section is marked in yellow your corsor is above it
   • The Plots can be run independently, as long as the init-part has been run

Misc. Matlab-tips

• close all

  • Closes all plots

• sim('simulink_filename')

  • Runs a simulink-simulation. The filename is without the .slx - ending
  • Does not build anything

• Use a to file-block to get data from a simulink-simulation to a .mat -file
  

  • Remember to change the output-type to array

• load('filename')

  • Get the variable(s) from the .mat file to the workspace (filename is without .mat)
  • The first row of the matrix is time, the rest are in order of input.

• save filename

  • Lets you save the current workspace as filename.mat
  • Can be called without any parenthesis or quotation-marks

Not implemented:

• Titles in Plots with multiple subplots
• Rotating the y-label and changing its position
• Adding LaTex-code to the labels and legends
