making rectangular matrix by non rectangular matrix by putting zeros
显示 更早的评论
Hello, I have a text file data which every row has different numbers which the longest is 17 numbers. If the number of rows be n, how may I make a matrix n*17 which put zero at the end of those rows which have fewer numbers than 17? As an example this data which should be 10*17 matrix.

One approach:
c = {[1 1]; 2; [3 2 2 4 2 2 2 3 3]}; % Original Cell Array (Segment)
szc = cellfun(@size, c, 'UniformOutput',false); % Sizes Of Each Vector
M = zeros(size(szc,1), max([szc{:}])); % Preallocate
for k1 = 1:size(M,1)
M(k1, 1:szc{k1}(:,2)) = c{k1}; % Fill Each Row
end
