random grouping of users and subcarriers

Please anyone help me to execute the following code. clear all; clc;

N_UE=[2 4 6 8 10]; N_SC=[20 30 40 50 60];

t= 1:length(N_UE) r = 1:length(N_SC)

s= randperm(length(N_UE)) p= randperm(length(N_SC))

G = rand(s,p)

What do you want to do with it?

i want to have random selection of users and subcarriers.

You want to randomly pick from N_UE or N_SC?

Change this line

G = rand(s,p)

to this

G=[randsample(N_SC(r),1) randsample(N_UE(p),1)]

It worked thanks a lot.Now if I want to group users randomly there by sharing the subcarriers among the group

how the following command can be modified

numGroups = 5; % Need to divide G up into 5 groups

divisions = sort(randperm(numUsers, numGroups) , 'ascend')

divisions = [0, divisions, numUsers]

% Create cell array with random number of users in each groups

groups = cell(1, numGroups);

for k = 1 : numGroups

indexes = divisions(k)+1:divisions(k+1);

% Assign users to the kth group:

usersInThisGroups = length(indexes);

fprintf('Assigning %d users (indexes %d to %d) to group %d.\n', ...

usersInThisGroups, divisions(k)+1,divisions(k+1), k);

groups{k} = s(indexes);

end

celldisp(groups); % Display groups in command window.
