Plotting 4-D arrays in 2-D graph

Hello, I am a newbie to matlab. I have a question about generating a plot.
My code is as follows. The irfStd is a 3x20x800x33 4-D matrix. The size(irf1,4) = 800.
I am wondering why I can't generate plot using this code and matlab kept reporting 'Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses.'
Thanks in advance.
lb=floor(size(irf1,4)*.16)+1; % lower band
ub=ceil(size(irf1,4)*.84)+1; % upper band
plot(1:20,squeeze(median(irfStd(2,:,:,11),3)),'k',1:20,squeeze(irfStd(2,:,[lb ub],11)),'--k')...
axis tight, title('Inflation')

The axis command and title command are not part of the plot command but you continued them on the same line without a separator. Just replace your last few lines with
plot(1:20,squeeze(median(irfStd(2,:,:,11),3)),'k',1:20,squeeze(median(irfStd(2,:,[lb ub],11),3))','--k')
axis tight,
title('Inflation')
