How can I skip empty cells when averaging during a function?

Hi,
I have a function in which I average the values of the doubles within each cell of a cell array.
for i = 1:length(explained_balls)
explained_pc1_avg_part_x_phase(1,2) = mean(explained_balls{i}(1,:));
end
Because I have a cell which is empty I get the error
Index in position 1 exceeds array bounds.
I was wondering if I can write the functiion so that it skips the empty cell and doesnt throw the error? Help is greatly appreciated.

load explained_balls
whos
for i = 1:length(explained_balls)
%explained_balls{i}
if isempty(explained_balls{i})
explained_pc1_avg_part_x_phase(i) = NaN; % or 0
else
% explained_pc1_avg_part_x_phase(1,2) = mean(explained_balls{i}(1,:));
% The above find average of the 1st row, which is a single number.
% Check it out!!!
explained_pc1_avg_part_x_phase(i) = mean(explained_balls{i});
end
end
explained_balls
explained_pc1_avg_part_x_phase
