Error: "Not enough input arguments"

Here is the code that I have written so far:

function out = repvec(vec, s)

vec_size = size(vec);
num_row = vec_size(1);
num_col = vec_size(2);

if num_col == 1
    vec = vec';
end

out_vec = [];

if s == 0
    out = []
elseif num_row == 0
    out = []
else
    for i = length(vec)
        for j = 1:s
            out_vec = [out_vec, vec(i)]
        end
    end
end
out = out_vec;
end
I am getting the error tha

t there are not enough input arguments, and an error in the line with vec_size = size(vec). I am fairly new to MATLAB, so any help would be appreciated!

You cannot invoke that code by just pressing the green Run button. You need to either call it from a function or script, or else you need to go to the command line and invoke it, passing in apropriate data.

For example:

repvec( sprintf('bottles of beer on the wall\n'), 99)
