How to solve error for Index exceeds matrix dimensions

for k = 1:1:(length(n_taylor_range))

     S = n_taylor_range(k);

     ys_taylor(1:(length(t))) = 0; 
     xs_taylor(S,1:(length(t))) = 0.; 

      for w = 1:1:S  

        xs_taylor(w,:) = -((K(w)*pw*cos((2*pi*k(w)*t)/pw))/(2*k(w)*pi)); 
        ys_taylor = xs_taylor(w,:)+ys_taylor;

      end  

     yss_taylor(k,:) = ys_taylor;
     P_taylor(k,:) = (fc*t)+(((bw*(t.^2))/(2*pw))+ (bw*yss_taylor(k,:)));

end

YOu have not given all the variable and did't specify the error line. And note that this error comes when you try to extract more number of elements then existing in the data.

Thanks Mr siva,

the all code like this :

    %Parameter specifications of chirp signal%
    fc = 0*1e6; %Frequency Carrier (MHz)%
    bw = 10*1e6; %Bandwith (MHz)%
    fs = 100*1e6; %Frequency sampling%
    pw = 100*1e-6; %Pulsa Width (us)% 
    t = -(pw/2):(1/fs):(pw/2); %time%
    th = 2*min(t):(1/fs):2*max(t); %time of convolution%
    n = length(t); %Number of Sample%
    nt = length(th); %Number of Sample Xcorr%
    n_taylor_range = 1:1:30; %Taylor Range Coefficients
    n_taylor = 3; %Choose The Taylor Coefficients

     k = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30];

      for k = 1:1:(length(n_taylor_range))
           S = n_taylor_range(k);
           ys_taylor(1:(length(t))) = 0; 
           xs_taylor(S,1:(length(t))) = 0.; 
            for w = 1:1:S  
              xs_taylor(w,:) = -((K(w)*pw*cos((2*pi*k(w)*t)/pw))/(2*k(w)*pi)); 
              ys_taylor = xs_taylor(w,:)+ys_taylor;
            end  
           yss_taylor(k,:) = ys_taylor;
           P_taylor(k,:) = (fc*t)+(((bw*(t.^2))/(2*pw))+ (bw*yss_taylor(k,:)));
      end

I think, the error in this code :

for w = 1:1:S  
        xs_taylor(w,:) = -((K(w)*pw*cos((2*pi*k(w)*t)/pw))/(2*k(w)*pi)); 
        ys_taylor = xs_taylor(w,:)+ys_taylor;
      end

perhaps you can help me,

thanks

You have written this between the code which is creating error.

   k = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30];
        for k = 1:1:(length(n_taylor_range))
             S = n_taylor_range(k);

Loop index and the variable both are assigned by the same variable. So, try using different variable for the loop indices.

Now, your code runs successfully.

kk = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30];
      for k = 1:1:(length(n_taylor_range))
           S = n_taylor_range(k);
           ys_taylor(1:(length(t))) = 0; 
           xs_taylor(S,1:(length(t))) = 0.; 
            for w = 1:1:S  
                w
              xs_taylor(w,:) = -((K(w)*pw*cos((2*pi*kk(w)*t)/pw))/(2*kk(w)*pi)); 
              ys_taylor = xs_taylor(w,:)+ys_taylor;
            end  
           yss_taylor(k,:) = ys_taylor;
           P_taylor(k,:) = (fc*t)+(((bw*(t.^2))/(2*pw))+ (bw*yss_taylor(k,:)));
      end  

for w = 1:1:S  
        xs_taylor(w,:) = -((K(w)*pw*cos((2*pi*kk(w)*t)/pw))/(2*kk(w)*pi)); 
        ys_taylor = xs_taylor(w,:)+ys_taylor;
      end
