Hi,
I have a 1x7 cell array. Each cell contains a 48x57 matrix. I want a scatter plot of row 10, column 2 from cell 1-7 like: scatter(SNR{1, 1:7}(10,2),SNR{1, 1:7}(10,3)) This approach doesn't work. Any idea how I can manage this?

"Doesn't work" is a weak description of the problem. Prefer to post the error message instead of hoping, that the readers can guess it.

Working with cell arrays is not useful here. Simply convert the data to a numerical 3D array at first:
SNRd = cat(3, SNR{:});
scatter(SNRd(10, 2, 1:7), SNRd(10, 3, 1:7))
Maybe additional reshape commands are required to create vectors.
