17 Jul 2014 Fraunhofer Diffraction of Light by a Rectangular Aperture This code calculates the diffracted intensity pattern for a rectangular aperture Author: Sathyanarayan Rao

Hello Igor, Thanks and appreciation for the positive feedback. Best Regards

03 Jul 2014 Magnetic field of a Circular current loop using Biot Savart's Law Magnetic Field of a circular loop is evaluated in two dimensions. Author: Sathyanarayan Rao

Hi Brett,

The purpose of this code was just to calculate field patterns. The units were all arbitrary. One can always normalize and scale to desired units. This code implements Biot Savart's law without giving importance to units of physical quantities which can be anything.

Thank you

01 Nov 2013 Diet Problem in Linear Programming The goal of Diet problem is to minimize the cost of food satisfying nutrient constraints. Author: Sathyanarayan Rao

Hi Scott Richardson,
An objective of standard linear program problem is to maximize or minimize a vector c'x, subjected to the condition L<Ax<H. In this problem, we are trying to minimize the cost and lower bound L and upper bound H are given by lower and upper bounds on nutrients. So the condition matrix A should be the A_new matrix you are asking about. I have referred this textbook and I would suggest you also ,if you are interested more on Diet problem. Text: Linear Programming by Robert Vanderbei. Thanks
