I assume that the requirement is to store the 2 outputs of ttest_bonf (i.e., H, P) into a cell array. In that case the variable needs to be initialized as a cell array. The following code illustrates the idea:
h_p = {false(size(column,1), size(testdata,2)), zeros(size(column,1), size(testdata,2))};
h_pcell = {h_p, h_p, h_p};
The h_p denotes a cell array in which the first and second elements stores the 1st and 2nd outputs of 'ttest_bonf' function for each input.
h_pcell is also a cell array whose elements are of cell type. It is used to store the outputs of ttest_bonf function for the ‘testdata’ which is a 1x3 cell. The following code illustrates this:
for c=1:(size(testdata,2))
for f=1:size(column,1)
[h_pcell{c}{1}(f,:), h_pcell{c}{2}(f,:), ~] = ttest_bonf(table2array([testdata{1,c}(:,column(f,1)) testdata{1,c}(:,column(f,2)) testdata{1,c}(:,column(f,3))]));
end
end
You may refer to the documentation of cell indexing, multilevel indexing & table indexing for more information on initializing & indexing rules.
