Answer to Question #45547 in MatLAB | Mathematica | MathCAD | Maple for VISHNUJITH

Question

Write a single program that calculates the arithmetic mean (average), rms average, geometric mean and harmonic mean for a set of n positive numbers. Your program should take two values xlow and xhigh and generate 10000 random numbers in the range [xlow…xhigh], and should print out arithmetic mean (average), rms average, geometric mean and harmonic mean.
The definitions of means are given as follows.

Answer 1

% Input
xlow = input('xlow: ');
xhigh = input('xhigh: ');
 
% Random array
array = randi([xlow xhigh], 1, 10000);
 
% Arithmetic mean
AM = mean(array); 
% Quadratic mean
QM = sqrt(mean(array.^2));
% Geometric mean
GM = geomean(array);
% Harmonic mean
HM = harmmean(array);
 
% Output
fprintf('Arithmetic mean: %.3f\n', AM);
fprintf('Quadratic mean: %.3f\n', QM);
fprintf('Geometric mean: %.3f\n', GM);
fprintf('Harmonic mean: %.3f\n', HM);
