Perhaps you may try to obtain the random row from your matrix with this code:

C = [1 2 3; 3 4 5; 6 7 8; 9 10 11; 12 13 14; 15 16 17];

N1 = 1;

N2 = 6;

r = randperm(N2, N1);

randomMatrixRow = C(r, :);

Hi, if I understand well, you need an integer random number generator.

You can use the 'randi' MATLAB function to generate random integers between 1 and the number of lines of your matrix. Best

Dear Anita Zade,

Also you can use function called randsample in Statistics Toolbox or like sayed Prof Richard Epenoy use "randi" in Matlab.

Best regards

Here is another piece of code (according to colleague Richard Epenoy):

C = [1 2 3; 3 4 5; 6 7 8; 9 10 11; 12 13 14; 15 16 17];

sz = size(C);

r = randi(sz(1));

randomMatrixRow = C(r, :)

You can usa the randperm function

Row = C(randi(length(C),1,1),:)

To Kiarash Aryankia: it is such a neat piece of code!

Very grateful to see all the optional answers.

For me randsample function worked perfectly.

c=[1 2 3; 3 4 5;6 7 8;9 10 11;12 13 14;15 16 17 ];

[m,n] = size(c )

idx = randsample(m,1 )

iwant = c(idx,:)
