combine celle array of cell array vertically

14 views (last 30 days)
Hi, I have a cell arrays of cell array 'ABC'. Rows of ABC represent data from different experiment. Columns of ABC represent different type of measurement for experiments. for example columns 1 is the time stamp of each sample. at the moment i have a m*n cell array of cell array. I want to concatenate ABC so i end up with a cell array of cell array with a dimension of 1*n. Any ideas? I used
vertcat(ABC{:})
but it concatenates the all data into 1 colunm, i want to keep my colunms... Cheers

This
cellfun(@(col) vertcat(col{:}), num2cell(ABC, 1), 'UniformOutput', false)
or
arrayfun(@(col) vertcat(ABC{:, col}), 1:size(ABC, 2), 'UniformOutput', false)
will do what you ask. The 2nd one may be faster.

You can use reshape to convert your mxn cell array into any desired size. As you want to convert it to column. Use:
A = reshape(ABC,[],1) ; % 1 specifies the column, [] matlab decides the number of rows (=m*n)
