MATLAB: How to delete elements from cell arrays

Question

Hi, I have a cell array(1×316) which contains 316 double

numeric arrays of various sizes like 74845×1,81032×1,55434×1 and so on.

I want to delete data values from each array cells which is greater than 140 and save it in a new cell array.

Format of my data looks like below:-

inst_speed_all_user_rome.mat(cell array)->speed_kmh(variable)->

1 2 3 … ….316(total 316 cells of arrays)

{74845×1 double},{81032×1 double},{87351×1 double},…..

sample of one array inside one of those 316 cells :

speed_kmh{1,1}-> {74845×1}= 44.889 28.445 0 156 33.46 ……..

Now, for above scenario,i need to delete the data 156(which is greater than 140 here) likewise i want to delete all data values > 140 from all arrays.

Initially i have stored cell array in s1 which is a 1×1 struct with one field ->speed_kmh of size 1×316.

Please help me out on this.

This is my code but i am stuck.

    %%store cell array in struct s1
    s1 =load('inst_speed_usr_rome.mat');
    %%delete the values greater than 140 from cells 
    l = s1.speed_kmh{:};    
    to_delete = false(size(l));
    for i=1:length(s1.speed_kmh)
    if (s1.speed_kmh(i)>140)
    to_delete(i) = true;
    end
end
l(to_delete) = [];

Answer 1

Perhaps:

s1 = load('inst_speed_usr_rome.mat');
for k = 1:numel(s1.speed_kmh)
  v               = s1.speed_kmh{k};
  s1.speed_kmh{k} = v(v <= 140);
end
