MATLAB: How to extract the data from cell to normal matrix

cellextract data

Hi everybody,

I am looking for an answer to my problem. I have 1×600 cell data which every cell contain 1888×4 matrix. The first column is x, the second is y, the 3rd is u and the 4th is z. I would like to collect all of x column into 1 matrix. In the end, I will have x_collection = 1888×600 matrix.

Does anyone know how to do it? I am a newbie here. Really appreciate your help

all_x =  cell2mat( cellfun(@(C) C(:,1), YourCell, 'uniform', 0));

MATLAB: Calculate mean and std in every matrix component in different cell

Hi,

This should work if I am understanding you correctly. Do you basically want to match up all the corresponding matrices in each cell component and produce a mean and standard deviation of them?

z = 600;
cellData = cell(1,z);
x = 1888;
y = 4;
matrixData = rand(x,y);
cellData(:) = {matrixData};
means = zeros(x,y);
stdevs = zeros(x,y-2);
for ii = 1:x
for mm = 1:y
  data = zeros(1,z);
  for rr = 1:z
    data(rr) = cellData{rr}(ii,mm);
  end
  means(ii,mm) = mean(data);
  if (mm == 2 || mm == 3)
    stdevs(ii,mm-1) = std(data);
  end
end
end
means = {means} %These lines makes the outputs into cells.
stdevs = {stdevs}

Hi!

Try

   C{1, 1} = {'11'; '12'};
   C{2, 1} = {'21'; '22'};
   C{3, 1} = {'31'; '32'};
   Rows = 3;
   Columns = 2;
   CO = reshape([C{:}], Columns, Rows).';
   Newc = cell(1, Columns);
   for n = 1:Columns
       Newc{n} = {CO{:, n}}.';
   end
