how to generate random integer number in a fixed range in MATLAB, like between 1 to 10

i want to generate random number between 1 to 10 answer like: 7 4 1 8 5 2 10 6 9 3

[Siddharth Gupta]

x=randi([1,10],1,10);

Answer 1

[Sean de Wolski]

doc randi

and simple example:

randi([1 10],40)

[Hassaan]

If repititions are not required:

c = randperm(20);
disp(c)

     5    15    18    17     1    19    14    16    10    20    12     9    11     2     3     4    13     7     8     6

If repetitions are not wanted:

c = randperm(10);

[Shamsuddeen Abdullahi]

Please, what if I want repeatitions?

[Yifu Luo]

randi([min max], [size_x, size_y])

[Priodyuti Pradhan]

It is perfectly working! Thank you for sharing!

I was tryingh to fit some variables using nlinfit for which i have generated random integers with randi but after fitting it has chosen some values as decimals numbers. If I can get any specific reason for the same?

We would need to see your code, GAGANDEEP KAUR

Hii...Prioduyti and others...How to use this code with a component used in simulink .I want to use randi function with a component of matlab simulink (lead screw)..how to link this function with that....Please guide.

Use randsample

if the range is 1 to n:

y = randsample(n,k) returns k values sampled uniformly at random, without replacement, from the integers 1 to n.

if the range is say 8 to 23, choose 6 randon mumbers

population = 8:23;

y = randsample(population,6)

y = randsample(population,k) returns a vector of k values sampled uniformly at random, without replacement, from the values in the vector population.
