This program results in two graph outputs. 1.Drag force vs Velocity ( Co-efficient is constant, velocity varies) 2.Drag Force vs Drag Coefficient (Velocity is constant, Drag Coefficient varies) The Drag force vs Velocity Graph shows that for increasing velocity the force increases exponentially since velocity^2 is…

NASA FILE PARSING The following codes are used to parse the thermo30.dat file and extract the values used for calculating the entropt, enthalpy, specific heat and molecular weights of several compounds. Then they are plotted vs temperature. Main program clear all close all clc file = fopen(\'thermo30.dat\',\'r\'); head1…

Section 1 The genetic algorithm is a method (function in MATLAB) for solving both constrained and unconstrained optimization problems that is based on Charles Darwin\'s Theory of Natural Selection, which says the fittest among the group survives. GA generates a number of points at each iteration. The best point in the…
