Plotting data with Octave
Overview
In this tutorial, we will learn detailed steps to plot data using an Octave script.
Sample function
We can choose any function. Let’s choose a simple function y defined as:
y= 1/(x^2 + 1);
Generate x vector with some sample points from 0 to 10.
x=linspace(0,10,100);
Calculate y vector.
y= 1./(x.^2 + 1) ;
Steps to create Script
Launch Octave.
File >> New >> New Script
File >> Save File to save the file.
Plot command
%Plotting data using OCtave x=linspace(0,10,100); y= 1./(x.^2 + 1) ; %Plot graph figure %plot command plot(x,y,'ro','MarkerSize',30) xlabel('x') ylabel('y') title('Sample Plot');
