Indexing all the row data for each column

Hi everyone,
For example, if I had a matrix with 10 rows but variable column lengths for each row how would I iterate "for all row datapoints within each column"?
Right now using A(1:end,1:end) returns the entire matrix, but I would need to isolate each column of data.
Thank you in advance

You can't have non-rectangular arrays in Matlab.
You can approximately get the same effect by using a cell array, or by padding with NaN. The most optimal strategy will depend on what you want to do.

For a 2D matrix, you can access a row as follows:
% Matlab indexing is row major
% return single row of matrix A
A(1,:)
A(2,:)
A(end,:)
%return single column of A
A(:,1)
A(:,2)
A(:,end)
