Hello,
I'm new to MATLAB and still learning :) I've been struggling with one such command execution.
I have a cell array c28_20chs which has 5 cells inside it as shown in the picture. I need to navigate to the individual cells and then plot col 3,4 together as x anf y axis.
Is there any structured command for it? I would really appreciate if any one could guide me.

for i=1:numel(c28_20chs)
hL(i)=plot(c28_20chs{i}(:,3),c28_20chs{i}(:,4));
if i==1, hold on; end
if isempty(c28_20chs(i)), continue, end
end
Read the background info on cell arrays for examples and explanation of dereferencing cell arrays.

Hello dpb.
Thanks for the code. Its indeed plotting the data, but i get an error-"Index in position 2 exceeds array bounds". What is this about?
Also can you please provide me a link to the -"background info on cell arrays for examples and explanation of dereferencing cell arrays" or suggest some keywords for me to find the correct info :)
Thanks!

Paste the error in context -- not having your data can't duplicate here.
As for the information on cell arrays, start with
doc cell
It has examples; there's also the links under "Topics" at the bottom of the page, one of which is titled <Access Data in Cell Array>.
