%% 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?

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

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
