## Mathematics Matrix Manipulation in MATLAB

This article is simplest guide for matrix manipulation in MATLAB which a programmer need for a regular work. Everything is treated as a matrix in MATLAB. Ex- a=1; which is a scalar means a matrix of one row and one column which contains the element ‘1’. You can read this in article an introduction to MATLAB Matrix […]

## HOW TO MANIPULATE GRAPHS IN MATLAB

Basics of Plotting Graphs in MATLAB In this article we will see that how commands like plot, stem, subplot, xlabel, ylabel, title, plot, stem, subplot, axis, plot3, colour, linewidth, hold and legend are used in Plotting graphs in MATLAB. ( if you are new to MATLAB, first check this article to learn basics of MATLAB) Introduction to […]

## Filter Inductor Design

Design Calculations for Filter Inductor Design Calculations for filter inductor of ferrite core will be explained here. These inductors are common and essential part of power electronic converter circuits. Main objective of inductor in converter circuits is to eliminate unnecessary harmonics in circuit to get smooth output. As in power electronic devices switching is very […]

## Generalized Assignment Problem using LP Solver

LP Solver: To understand Generalized Assignment Problem using LP Solver, Lp solver is first need to understand. Lp solver is software to solve linear programming optimization problems. This gives you simplest interface to write optimization problem and provide optimized solution. Just formulate the optimization problem in standard Linear Programming (LP) form and write accordingly in command […]

## Generalized Assignment Problem using Excel Solver

1. Introduction: 1.1. Generalized Assignment Problem In Generalized Assignment Problem for optimization is daily life problem in which we have n number of tasks/assignments and m number of machines/labor available to perform that tasks. Each machine/labor have some cost for performing specific task. There could be time constraints for each worker to do specific job […]

## Transformer Design Turns per Volts

Transformer Design Turns per Volts In previous article, we derived a formula for turns per volts of transformer winding for transformer design. That formula has core area involved in it. Now, we are going to derive a formula for transformer design turns per volts according to transformer ratings and depending upon type of transformer […]
