How do I delete empty rows in a matrix?

%% Combine the data %combined = [6050,54]% define size of combined

SWOA = zeros(100,5); CWOA = zeros(100,5); SWA = zeros(100,5); CWA = zeros(100,5);

for i = 8:length(mydata)%loop to group data together into jump types

   if grouped(i,4) == 1 % if data = 1 put in squat without arms

        SWOA(i,1) = grouped(i,1);

      else if grouped(i,4) == 2 % if data = 2 put in counter without arms

            CWOA(i,1) = grouped(i,1);

          else if grouped(i,4) == 3  % if data = 3 put in squat with arms

                 SWA(i,1) = grouped(i,1);

              else if grouped(i,4) == 4 % if data = 4 put in counter with arms

                    CWA(i,1) = grouped(i,1);

                  else if grouped(i,4)== 0

                          continue 

                      end
                  end
            end
        end
    end
end

emptyCells = cellfun('isempty', SWOA);

SWOA(all(emptyCells,2),:) = []

In the variable SWOA for example it looks like this:

I am trying to delete all rows that have 0's in so that I am left with only about 5 or 6 rows of data that can be processed, how would I do this?

Answer 1

[Honglei Chen]

CWOA(all(CWOA==0,2),:)=[]

[Franchesca]

does this replace these lines:

emptyCells = cellfun('isempty', SWOA);

SWOA(all(emptyCells,2),:) = []

Thank you

These are slightly different. Your code works for cells, and it is indeed looking for empty cells. But empty cell is different than a matrix that has all zeros. My code for the latter.

Your code would work for things like

x = cell(2,3)
x(2,3) = {1}

It will remove the first row
