function requires more input arguments to run

this is my context:

function [v_time,v_frec,stft_fd,elapsed_time]=STFT_FD1(v_t,x,Ts,NC) 
initial_time=cputime;
NS=size(x,2);
    v_time = v_t(1+(2*NC/2):NS-(2*NC)/2);
    v_frec = [];
    v_p = [];
    stft_fd=[];
    for p=2:NS/NC
        v_frec = [v_frec, 1/(p*Ts)];
         v_p=[v_p,p];
        NW=p*NC;
      window=hamming(NW)';
        for t=NW/2:NS-NW/2
           wx=window(1:NW).*x(t-NW/2+1:t+NW/2); 
             fft_wx=fft(wx);
            stft_fd(t,p)=fft_wx(1+NC);
        end;
    end; 
    %Calculate the elapsed time
    elapsed_time=cputime-initial_time;
end

is there any need to build it please help us to find out.
