Count number of smaller than the threshold in the certain rows of cell arrays

Dear all,
I have a 1 x 3 cell array, each 3 array includes 360x1 double. For each 1 to 360 rows stored in every 3 arrays, I want to know how many times I have smaller than -0.5 values. For example, I want to consider all first rows in each array and count that there is any smaller than -0.5 exist in them. Then consider all second rows in each array, and so on. I don't want to look at each array individually but I need to consider every row in all arrays as integrated rows.
So input is 1 x 3 cell array. And the output is: 3 x 1 double (number of times each row has smaller than -0.5 values)
Any advice is really helpful
Thank you.

sum(cell2mat(CELL)<-0.5,1).'

What you described cannot lead to a 3x1 double vector, which is what you said you expected the output to be. However, the modification you're talking about is simply,
sum(cell2mat(CELL)<-0.5,2)
Generally, speaking there doesn't seem to be any reason for you to be holding your data as a cell array. You should just make it into a 360x3 double matrix,
C=cell2mat(CELL);

Thank you so much, Yes you right. This was exactly what I needed.
Best Regards.
