Compare cells in cell array to find common columns

1 view (last 30 days)
I have two cell arrays, data 1 (1x6 cell) and data 2 (1x8 cell) where each cell consists of 3x5 double or 3x4 double. I would like to compare these cell arrays and find out which cells have at least two columns in common, e.g. data1{1,1} and data2{1,1} have two columns in common. Then I would like to store all these cells in a new cell array.
What is the best way to do this?

You should just use an explicit loop over all combinations of cells. With cell arrays, there is never a good reason to look for some kind of fancy vectorization, and certainly not with arrays as small as what you've posted.

Thank you for your answer. Which function would you suggest I use to be able to find the common columns if the cell arrays and the cells have different sizes?

You can transpose the matrices and use intersect(__,'rows') if the agreement between columns is to be exact, otherwise ismembertol(__,'ByRows', true)
