#Gnu octave electrical engineering code
The code "as provided" in book was initially run in OCTAVE and error / warning messages in OCTAVE were rectified.

Few of the examples on this page are adaptation of MATLAB codes available in book "Mechanical Vibrations" by Singiresu S. OCTAVE scripts are highly compatible to MATLAB. However, there is certain process which needs to be followed such as a higher order ODE needs to be converted into a set of linear ODE. This is a great tool where user do not have to write any code, just specify the boundary and initial conditions. OCTAVE can be used to solve partial differential equations and set of ordinary differential equations numerically. Numerical solutions with GNU OCTAVE is presented for transient heat transfer, mechanical vibrations, motions of slider crank mechanism, system of ODE, motion of a projectile with viscous drag, optimization using Least-Squares Optimization, Linear Programming and Sequential Quadratic Programming (SQP) methods to name few applications.

Students belonging to Final Year/Pre-Final year or working professionals Prerequisite:īasic theoretical knowledge in Electrical/ Electronics/ Instrumentation Engineering, further we will teach the application and methodologies related to solving Engineering problems. It’s similar to GNU Octave and 95% compatible with Matlab.
#Gnu octave electrical engineering software
Scilab is a free and open source software for numerical computation providing a powerful computing environment for engineering and scientific applications including maths, simulation, optimization, control systems, signal processing, signal modelling, image enhancement, fluid dynamics. We will teach the basic domain knowledge in addition to mathematical implementation with multiple projects related to the real world applications. The objective of this course is to learn and solve Engineering problems using Open source software Scilab. SCIENTIFIC COMPUTING FOR ECE / EEE / EIE (USING SCILAB/MATLAB/GNU OCTAVE) OBJECTIVE:
