Getting started with GNU Octave

Getting started with GNU Octave

The GNU Octave tutorial videos from Coursera and includes basic Octave tutorial which might be helpful for beginners.

Here are the tutorials

Basic Octave input output

Playing with data

Using scripts to better performs computations

Plotting 1D and 2D data

Working with control statements, while, for, etc.

This video shows how to speed up computations by using vectorization or using arrays and array indices. This is an essential way of getting around Octave’s parser since Octave doesnot have and JIT capability at the moment. Instead of calling a compiled function several times and reads the output, call it one time with an array which speeds up the script performance in terms of calculation time.
