Hi all,
I have a 21x1 cell with 100x 18 tables
I am calcuating mean of:
row 1, column1, all tables
row 2, column1, all tables
....
row 100, column 1, all tables
I repeat for remaining 17 columns, so ultimately, I have a table 100x18.
table=zeros(100,18);
for k=1:18
table_mean=table+table2array(my cell{k});
end
table_mean= table_mean/18
Howewever, some of the columns in a few tables have only 'nan' values. Is there a way to omitt those columns in my calculations?

This omits all NaNs from the mean calculation.
load('mycell.mat');
n_tables = numel(t_sq_dot_1);
% put all tables' data into a 3D array: 100x18x21
all_data = zeros([size(t_sq_dot_1{1}),n_tables]);
for ii = 1:n_tables
all_data(:,:,ii) = table2array(t_sq_dot_1{ii});
end
% alternate approach, using cellfun() and {:,:} indexing instead of
% a for loop and table2array():
% all_data = cellfun(@(x)x{:,:},t_sq_dot_1,'UniformOutput',false);
% all_data = cat(3,all_data{:});
% take the mean along the 3rd dimension, omitting NaNs
table_mean = mean(all_data,3,'omitnan');
disp(table_mean)
