Plotting MATLAB data from arrays with several dimensions

Question

Consider the three-dimensional arrays

A = rand(3,4,5);
B = rand(3,4,5);

plot(A(:,1,1),B(:,1,1))
plot(A(1,:,1),B(1,:,1))

This all works fine, however

>> plot(A(1,1,:),B(1,1,:))
Error using plot
Data may not have more than 2 dimension

Is there a quick way around this a way around this other than using reshape()?

you should use squeeze to remove singleton dimensions:

plot(squeeze(A(1,1,:)),squeeze(B(1,1,:)))

another option is to shift matrix dimensions using shiftdim

plot(shiftdim(A(1,1,:),1),shiftdim(B(1,1,:),1),'o')

Thanks natan, I was unaware of squeeze().
