Plotting random numbers in histogram and bin allocation.

Hi all

i have a set of 100 random numbers from 0-1, i need to plot these on a histogram and allocate them to 10 bins.

the program also needs to calculate mean and standard deviation.

i am unsure on how to do this on matlab and any help would be much appreciated.

here is the random number code i have currently.

Thanks !

clear all 
clc


n = 100; % However many numbers you want.
randomNumbers = randi([0, 1], [1, n])
randomNumbers = int32(randi([0, 1], [1, n]));

You have striaght away functions to achieve what you want. Read about histogram, mean, std.

ive looked at it i still cant work out how to apply it to this data

You have randomNumbers as only 0 and 1. So you will get only two bins.

x = rand(1,100) ;
histogram(x)

Thanks @KSSV, if i wanted to change the range of this. say from 0-50 now how would i do so and then alter the amount of bins?

youre help is much appreciated.

a = 0;
b = 50;
x = (b-a).*rand(1000,1) + a;
histogram(x)
