MATLAB: Separate Points for Plotting

Click For Summary
SUMMARY

The discussion centers on plotting 1000 data points in MATLAB, categorized into two classes based on their position relative to a decision boundary. Users seek guidance on visually distinguishing these classes by using different colors for class 1 and class 0 data points. The solution involves utilizing MATLAB's plotting functions to achieve this differentiation effectively.

PREREQUISITES
  • Familiarity with MATLAB programming environment
  • Understanding of data visualization techniques
  • Knowledge of basic plotting functions in MATLAB
  • Concept of decision boundaries in data classification
NEXT STEPS
  • Explore MATLAB's 'scatter' function for plotting categorized data points
  • Learn about customizing plot colors and markers in MATLAB
  • Investigate how to implement decision boundaries in MATLAB plots
  • Research data classification techniques relevant to MATLAB
USEFUL FOR

This discussion is beneficial for data scientists, MATLAB users, and anyone involved in data visualization and classification tasks.

Hi,

I have generated 1000 data points.
I have assigned them a class (1 or 0) depending if they are above or below a decision boundary.

I want to plot the data on a graph with the class 1 data points in one colour and the class 0 data points in another.

any ideasa how I can do this please?

Thanks!
