How can I fix this error : I using matlab version 2015

function [ofdm_tx, varargout] = ofdm_mod ( bin_tx, qam_t, n_cp, n_dsc, n_fft, n_sym, ofdm_t)
%% Local Variables: number of bits, samples, guard symbols, temp variables for interfunction calls
    n_bits_qam = log2( qam_t );
    n_samp_sym = n_fft + n_cp;
    n_bits_tot = length(bin_tx);
    n_grd = (n_fft - n_dsc)/2;
    flip_ofdm_call = 0;
    aco_ofdm_call = 0;
%% end section

See

https://www.mathworks.com/help/matlab/matlab_prog/calling-functions.html

https://www.mathworks.com/help/matlab/ref/function.html

You are running a function file. Apparently when calling a function you have to pass input arguments. See the example below:

x=1:10;  % define the input before passing in
D = samplle(x)
function D = samplle(x)  % function definition
D=x.^2;
end

Note : In versions prior to 2016b function definition have to be saved in a separate file containing the same name of a function but in 2016b or later a script file contain a function definition at the very end.
