I wanna plot sin wave, the source is from number binary "1 and 0" from notepad.
So, what should I do for plot sinus wave?
this my coding:
axes(handles.axes4)
mod=load('D:\Polinema\Akademik\SKRIPSI\Proyek Skripsi\GUI Proyek Skripsi\blokbaru\100 mod.txt','-ascii');
plot(mod,'b','LineWidth',1.5);
axis([1 100 -1.5 1.5]);
title('Output Modulator BPSK','fontweight', 'bold');
xlabel('Sample','color','b');
ylabel('Amplitude','color','b');
grid on;
guidata(hObject, handles)

That code looks plausible. Could you show us the first few lines of "100 mod.txt" ? What shows up for min(mod(:)), max(mod(:)), size(mod) ?

100 mod.txt contain various 1 and -1 binary. they are 1 -1 -1 -1 -1 1 -1 -1 -1 -1 -1 -1 -1 1 1 -1 -1 1 1 1 -1 -1 -1 -1 -1 1 -1 -1 1 -1 1 -1 -1 1 1 -1 1 -1 1 1 1 -1 -1 1 1 1 1 -1 -1 1 -1 1 1 -1 1 -1 -1 1 1 -1 -1 -1 1 -1 1 -1 -1 -1 1 -1 -1 -1 1 1 1 1 -1 -1 1 -1 1 1 1 1 -1 1 -1 1 -1 -1 1 -1 -1 1 -1 -1 -1 -1 1 -1

Hello Widya,
Your code is correct. I tried running same code and it is working fine and the result is as shown in below snapshot:
The result is not showing the sine wave because you providing the random 1 and -1 values in .txt file. So in order to plot the sin wave you need to provide such values into .txt file, so it will plot sin wave OR if you dont want to change these values, then apply some formula so that these value get converted into new values which will produce the sin wave while plotting it.
