formatting string with vectors

Hello,

As a part of my homework task, I need to write a function that formats an existing string with given variables which may be vectors or scalars and returns it in one cell array. for example,

num_participants = 3, experiment_num = 8:10

the output should look like, with no spaces:

exp experiment_number_sub10 participant number 
exp8_sub101
exp8_sub102
....
exp_10sub103

and all of this output should be in one cell array. So I figured out two ways and then got stuck:

    experiment_num = 8:10
    num_participants = 3
    f = cellstr(num2str((experiment_num)', 'exp%d_'))
    f2 = cellstr(num2str(([1:num_participants])', 'sub10%d'))

This works perfectly fine but I couldn't find a way to concatanate the two cell arrays into one (not in two coloumns but in one column)

and

    mat = [experiment_num',(1:num_participants)']

    list = sprintf('exp%d_sub10%d\n', mat)

only my output, in this case, is not in the right order

    list =

    'exp8_sub109
     exp10_sub101
     exp2_sub103
     '

though the columns themselves are aligned properly.

Your help is much appreciated (I read the documentation and googled anything I could, but I cannot understand how to proceed.

Thank you

You will probably have to run a for loop, but I usually like to just concatenate a string when I put in variables.

if true
 experiment_num = 8:10;
 num_participants = 3;
 for k = 1:length(experiment_num);
  list{k} = ['exp',num2str(experiment_num(k)),'_sub10',num2str(k)];
 end
end
