% Extract the matrix inside that cell in row 1, column 16
% of the cell array into a regular numerical array.
cellContents = ca{1,16}; % This is a regular normal matrix now
% Now extract row 816 from that matrix:
row861 = cellContents(861, :); % Get all columns of row 861 into row vector.

Just use two lines of code. There's no shame in doing this. And since MATLAB passes implicitly by reference anyway, it won't require a memory copy unless you change something.

Start here:
You can index into the cell array to extract its contents with {} or to extract the cell as ().
