How to generate random data which follows a specific pattern ?

I want to generate yearly Outdoor temperature data with 1 hr interval and having seasonal variation ( Summer, Winter ). There will be 8760 timesteps of data.In summer Temperature will vary around the range of 25-35 degree and In winter it will vary around -10 to 10 degree. I am a beginner in Matlab. Any suggestion or code reference would be very helpful

As KSSV said, the random function generates data very nicely. But this distribution might need to be adapted to your needs.

To adjust to your problem you need to add the desired mean of your data and multiply the distribution.

mean_temperature = 15*sin(0:0.1:6)+15;
random_variation = rand(1, 61)*20-10;
plot(mean_temperature+random_variation)

And if you want a non uniform distribution, you need to multiply the random_variation with a function instead of the value 20.

hope this helps you get started

[KSSV]

There is a inbuilt command rand in matlab which generates Uniformly distributed random numbers between 0 and 1. doc rand. To generate random numbers in a given range [a,b]. You may follow:

a = 50;
b = 100;
r = (b-a).*rand(1000,1) + a;

Thanks Yes , I already checked that command but It doesn't give any option to user to generate numbers that follow a certain pattern

Numbers follow uniform distribution. what pattern you are expecting?
