Cell computations - for loop

Hi, I have a variable RRI, which is a 1x48 cell, each cell being matrices of different sizes.

m = 0;
for num = 1:length(RRI{1,1})-1
    if (RRI{1,1}(num+1)-RRI{1,1}(num) > 50*10^(-3)*360)
        m = m+1;
    end
end

The code above works perfectly fine for one of the cells and when I do the computations individually for each cell. How can I (in a for loop for instance) do this for all 48 cells (RRI{1,i}, i = 1:48) and store the results in the variable m, which should also be a 1x48 cell?

Thanks!

You can add another “for” loop and use a cell array to store the result. Folllowings a sample code:

m = repmat({zeros(1,1)},1,48) ; % Initialize 
for i=1:length(RRI) 
n = 0; 
    for num = 1:length(RRI{1,i})-1 
        if (RRI{1,i}(num+1)-RRI{1,i}(num) > 50*10^(-3)*360) 
        n = n+1; 
        end 
    end 
m{i} = n; 
end

Thank you very much. It works perfectly!

Thank you. Your solution works!

How can I do the same for the following (see attached image): RRIseg is a 1x48 cell containing matrices of ROWx127. For all the cells, I want to compute exactly the same thing as above but along the rows of each matrix. For instance, if cell 1 is a 34x127 matrix, the result should be a 34x1 vector. How can I do that? Is it by using cellfun?
