ENGR132: HW07 - class6a_activity3

%  Program Description: Generate 1000 Gaussian random numbers with a mean
%  of 80 and standard deviation of 5 and makes a histogram out of the data.

% --- INPUTS ---
%Generates 1000 random numbers with mean 80 and stdev 5 in a 1000 by 1
%matrix.
rnd_num = normrnd(80,5,1000,1);

% --- CALCULATIONS ---
%Finds the mean of the data.
fprintf('\nMean of data: %f\n', mean(rnd_num));
%Finds standard deviation of data.
fprintf('Standard Deviation of data: %f\n', std(rnd_num));

%Finds the frequency of each bin and the center of each bin.
[Bin_frequency, Bin_centers] = hist(rnd_num)

%Sorts the random numbers.
sort(rnd_num);

% --- OUTPUTS ----
%Creates a histogram based on the given data.
hist(rnd_num);
