Color Targets for Imaging and Display devices
It is well established the requirement of accurate color (image) target for Photographers, Engineers & Scientists working on color profiling and Image and Video editors. A...
Octave:3> Data Visualization
Data visualization is the graphical portrayal of any data and information, summarized in a way that it is easy to see identify patterns and exceptions easily....
Octave:2> Functions
Function is a perfect way to implement a reusable code with ease of debug and maintainability.
Octave:3> File Operations
Generally Matlab/Octave scripts work on processing section of data which are generated from some kind of experiment or other events e.g. image processing. It is not possible for a user to enter value of each pixel manually in a processing algorithm. It is needed to read the image file directly and import data into variable in workspace.
Octave:2> Conditional Execution
Conditional execution and loop are the backbone of any algorithm. These maintain the proper flow of algorithm, for a successful execution.
Octave:2> Scripts and Algorithm
We need to change the settings, modify a variable. It is not convenient to retype everything. Scripts are the perfect solution or such cases which contains expressions in correct sequence
Octave:2> Vectors and Matrices Basics
Vectors and matrices are very useful for dealing with systems of linear equations and inequalities. This article takes more practical approach to use Octave/Matlab for Matrix operations.
DIY two-channel 120W DC power supply
DC power is the basic need for any electronics project to start. Though batteries are good for small projects and also recommended due to the stable supply of current. But with increased power demand for more sophisticated projects batteries don’t seem a very good option to work with. A good bench supply or power adapter is handy and can be easily procured, but there is no match for custom-tailored design, specifically suited for the need. This is the story of a DIY two-channel 120W twelve volts fixed DC power supply.
Octave:1> Built-In Functions, Commands, and Package
In mathematics, Function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. This concept is borrowed by programming languages to simplify the code by avoiding unnecessary repetition.
Octave:1> Expressions and operators
Expressions are the basic building block of statements in Octave. It can be created using values, variables that have already been created, operators, functions, and parentheses....
Octave:1> Variables and Constants
Octave showing the perfect compatibility with MATLAB keeps its tag of being called open source clone of MATLAB. This article is a continuation of the series dealing with variables and constants in Octave.
Octave:1> Getting Started
GNU Octave is a very powerful suite for its numerical, graphical, and programming capabilities. Despite being open-source this software suit can completely replace MATLAB (except few...
