Why do I get“Error using plot Vectors must be the same length."
显示 更早的评论
Please tell me how to correct it.
Ts = 0.001;
fs = 1/Ts;
To = 0.5;
t = 0:Ts:To-Ts;
N = length(t);
d = [0 1 0 1;0 0 1 1;1 0 1 0;1 1 0 0];
Ibranch = d(1:2:end);
Qbranch = d(2:2:end);
Im = [];
Qm = [];
for k1 = 1:length(Ibranch)
Im = [Im Ibranch(k1)*ones(1, N)];
Qm = [Qm Qbranch(k1)*ones(1, N)];
end
figure(1);
subplot(2,1,1);
plot(t, Im);
title('In-Phase Pulse Waveform');
xlabel('Time (s)');
ylabel('Amplitude');
subplot(2,1,2);
plot(t, Qm);
title('Quadrature Pulse Waveform');
xlabel('Time (s)');
ylabel('Amplitude');

Im = [];
Qm = [];
for k1 = 1:length(Ibranch)
Im = [Im Ibranch(k1)*ones(1, N)];
Qm = [Qm Qbranch(k1)*ones(1, N)];
end
What are you trying to do? Have you considered repelem ? Not that it is at all clear to me why you are replicating the values.

Make sure t and Im have the same number of elements.
Ts = 0.001;
To = 0.5;
t = 0:Ts:To-Ts;
N = length(t);
d = [0 1 0 1;0 0 1 1;1 0 1 0;1 1 0 0];
Ibranch = d(1:2:end);
Im = [];
for k1 = 1:length(Ibranch)
Im = [Im Ibranch(k1)*ones(1, N)];
end
size(t)
size(Im)

I'm not sure what you are trying to do. Best option may be to remove the for loop. Once you understand why this works, start adding to the code until you get a working final solution.
Ts = 0.001;
To = 0.5;
t = 0:Ts:To-Ts;
N = length(t);
d = [0 1 0 1;0 0 1 1;1 0 1 0;1 1 0 0];
Ibranch = d(1:2:end);
k1 = 1;
Im = Ibranch(k1)*ones(1, N);
size(t)
size(Im)
plot(t, Im);
title('In-Phase Pulse Waveform');
xlabel('Time (s)');
ylabel('Amplitude');
