Plotting data with Octave 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 […]

Introduction In this tutorial, let’s learn how to iterate over a vector in the Octave script. We will write an octave script to compute the average of numbers in a vector. We will iterate the vector using a for a loop. Octave Script function Average = IterateOverVector (numbers) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Given the vector of numbers […]

How to use fzero function in Matlab/Octave? Let’s discuss the usage of the Matlab function fzero function and how to use it in scripts. We can use the function to find the roots of the problem or values of the variable where the function tends to zero. Consider the below function: The problem of root […]

Matrix multiplication using Octave Let’s learn different matrix multiplication using the Octave or Matlab tool. In general, we will discuss two multiplications in this tutorial: Element-to-element Matrix-to-matrix   >> A = [1 2 3 ; 4 5 6 ; 7 8 9 ]; >> disp(A) 1 2 3 4 5 6 7 8 9 >> […]

How to specify Markers in Octave/Matlab Plot? Let’s learn the steps involved to specify markers in the Octave/Matlab plot command with attributes like edge color, face color, and marker size, etc. The octave script with comments shown below to plot the time vs velocity graph. Octave Script %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Sample Octave Plot % LineWidth = […]

Introduction In this tutorial, we will learn to plot a 3D Surface plot using Octave. Useful functions to plot in 3D are as follows : linspace meshgrid surf Code Listing % 3D Surface Plot Example % www.TestingDocs.com points = linspace(-3,3,100); [x,y] = meshgrid(points,points); z= -3./(1+ x.^2 + y.^2); surf(x,y,z); xlabel(“x-axis”); ylabel(“y-axis”); zlabel(“z-axis”); title(“Surface Plot Example […]
