how to remove empty cell array contents?

958 views (last 30 days)
Hello, I've got a cell array, lets say:
R =
[ 691x2 double]
[ 12x2 double]
[ 11x2 double]
[ 112x2 double]
[ 13x2 double]
Does anyone know of a quick way I could remove the non-zero elements of the cell array? This cell array will be a different length and will have a different number of non-zero elements each time, dependent on another loop
Thanks, Jim

I am also suffering from this problem. I want to delete the empty cells from this "sf" variable (i.e. shown in picture). I wish to delete it from variable so that whenever I try to find column size of the particular row; i'll be able to get only the matrix of that number cell and don't want to count the empty cell. for e.g. if i write
ans i want i.e. 5
but here it shows the 31
can someone help me to solve this problem?

There is no picture. What is the type of your variable sf? size(sf(3,:),2) replies the size of the array and does not care about the contents of the cell elements.
If you want to count the non-empty cells, use:
sum(~cellfun('isempty', sf(3, :))

D1 = D.';
out = reshape(D1(~cellfun(@isempty,D1)),2,[])';

>> data(~structfun(@isempty,data))
Error using structfun
Inputs to STRUCTFUN must be scalar structures.
