Undefined function or variable 'srrc_pulse'.

How can i fix this problem based on this code?

Fs = 10; %Sampling frequency
T = 1/Fs; %Symbol period
L = 1000; %Number of points
t = (0:L-1)*T; %Time vector
phi1 = srrc_pulse(1, 1/10, 4, 0); %SRRC pulse
figure
plot(Fs*t(1:50), phi1(1:50));
NFFT = 2^nextpow2(L);
Y = fft(phi1, NFFT)./L;
Y2 = fftshift(fft(phi1, NFFT)./L);
f = Fs/2*linspace(0,1,NFFT/2+1);
f2 = ((0:NFFT-1) -ceil((NFFT-1)/2))/NFFT/T;
figure
plot(f, 2*abs(Y(1:NFFT/2+1))); %one sided
figure
plot(f2, 2*abs(Y2)); %two sided

This is not an inbuilt function of MATLAB.

The error message shows the answer. You use the function "srrc_pulse.m" but you do not have srrc_pulse.m. If you know that you have it in the different directory, you need to set search path.

Please see the following page to set the search path https://www.mathworks.com/help/matlab/matlab_env/what-is-the-matlab-search-path.html
