GNU Octave

  • Built-in plotting and visualization1
  • syntax is largely compatible with Matlab
  • as a CLI tool or with GUI
  • Scientific Programming
    • Numerical Computation
    • Solves Linear and non linear problems
  • Written in C, C++ and fortran
    • Uses an interpreter to execute octave scripts

What is PI?

  • Where does it come from?
    • From a circle
    • IF we take the diameter of a circle and bend it to form a arc
    • and try to place it over the circle
    • It will take 3.14.... diameter arcs to complete the circle
    • mathematical prrof to the circumference of circle formula proof

$$ Circumference_{circle} \propto Diameter $$

$$ Diameter_{circle} = 2 * Radius $$

  • Linear Algebra
    • Vector Calculus
    • dot product
    • cross product
    • Matrix calculus
    • MAtrix inverse
  • Vectorization - using vector calulation instead of caluclation in for loops
  • Seeking help term
  • Random vectors and matrices
  • Load data from Files
  • The linspace() function generates linearly spaced vectors.
  • x = 1:0.1:10 from 1 to 10 in steps of 0.1
  • hold on prevent newer plot from erasing the older plot and redraw on top of it *
