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

• 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 *
