matlab - Set equal limits for y-axis for two figures -

how can make vertical axes of 2 plots equal?

for example:

a = [1 2 3; 21 1 3; 4 2 3; 4 5 6]

after plotting plot(a(1, :)) following figure:
enter image description here

i have done simple operations:

[u e v] = svd(a); figure(2); plot(u(1,:))

and figure: enter image description here

how make y-axis limits of both plots equal? axes equal command?

update:
i've used following commands:

figure (1) ylim([0 3]) plot(a(1,:)) figure (2); ylim([0 3]) plot(u(1,:))

but same result...

you can use ylim force limits on y-axis. example:

figure(1) %// plotting... ylim([0 3])  figure(2) %// more plotting ylim([0 3])

this ensures y-axis limited range [0, 3] in both plots. can same limits of x-axis command xlim.

also note if want set limits both axes @ once, instead of using xlim , ylim (two commands), can use axis (one command).
