Hi!
I have arrays of different length (length is different within each loop)
and I want to add the number of loop as the third dimension of each array. I used B(:,:,i)= B
What I get is B(:,:,1) = B @last loop (where i=4)
B(:,:,2) = 0 @second loop (where i=2)
B(:,:,3) = 0 @third loop (where i=3)
B(:,:,4) = B @last loop (where i=4)
What I want is B(:,:,1) = B @first loop (where i=1)
B(:,:,2) = B @second loop (where i=2)
until end of loop
I would highly appreciate if someone has a straighforward answer and can help, please!
for i = 1:4
%table of data different length*20 column
dim = data(data.TC_Counter3 == i,:);
%B is array of different lenghth*20
B = table2array(dim);
B(:,:,i)= B;
end

Save it as a cell instead of a 3D matrix since you say they are of different lengths.

B = cell(5, 1);
for ii = 1:5
dim = data(data.TC_Counter3 == ii, :);
B{ii} = table2array(dim);
end
celldisp(B)
