MATLAB: Applying Movmedian Within Cell Array

cell arraycellfunfunctionmedianmovmedian

Hello,

I have a cell array (2 x 6) called "output", each cell in row #1 {1 -> 6, 2} contains a 1024 x 1024 x 100 matrix. I want to apply movmedian to each cells in row #1. I would like to apply this function in dimension = 3 with window size = 5.

 output = cellfun(@movmedian(5,3), output,'uniform', 0);

This is the code that I have come up with so far, however, it produces an "unbalenced or unexpected parenthesis or bracket" error. I am unsure what is causing this error. I am also somewhat unsure how to instruct matlab to perform this operation only on row 1 of the cell array, please help!

Thank you for your time!!

output(:, 1) = cellfun(@(c) movmedian(c, 5, 3), output(:, 1), 'uniform', 0);

Remember, that cellfun is very nice, but less efficient than a simply loop in general. Try this:

for k = 1:size(output, 1)
  output{k, 1} = movmedian(output{k, 1}, 5, 3);
end

I prefer to keep it simple stupid, most of all if it takes less runtime in addition.

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

MATLAB: Create new column in cell array based on string values in other columns

Use strjoin to merge the strings and a loop to go over the rows:

C = {'aaa', 'b', 'cccc';
     'string1', 'string2', 'string3'}
newcol = size(C, 2) + 1;
for row = 1 : size(C, 1)
   C{newcol, 4} = strjoin(C(row, :), '_');
end

Or using cellfun instead of a loop:

newC = cellfun(@(row) [row, strjoin(row, '_')], num2cell(C, 2), 'UniformOutput', false)
newC = vertcat(newC{:})
