Question #45547

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 [xlowâ€¦xhigh], and should print out arithmetic mean (average), rms average, geometric mean and harmonic mean.

The definitions of means are given as follows.

The definitions of means are given as follows.

Expert's answer

`% 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**);**
