MATLAB: How to simultanously create 2 subplots

MATLABsimultanouslysubplot

Learned from Matlab, this worked:
figure;
for k = 1:8
h(k) = subplot(2,4,k);
end
figure;
for k = 1:8
J(k) = subplot(2,4,k);
end
But when call with after:
for k = 1:8
subplot(h(k);plot(a(k))
subplot(J(k);plot(b(k))
end
It plots 4-a and 4-b on the second figure and left the first figure with 8 empty subplots. What's wrong?

Best Answer

Your code
for k = 1:8
subplot(h(k);plot(a(k))
subplot(J(k);plot(b(k))
end
is not valid syntax: you cannot have a ";" at that position in the line and you are missing a ")" on each line.
You should be using
for k = 1:8
  plot(h(k), a(k), '*')
  plot(J(k), b(k), '*')
end
I added the '*' because you are only plotting a single point, and when you only plot a single point it will not show up unless you specify a marker.
