Hi, I have a cell array of size 1x316 with each cell of different sizes.All values in the cells are double numeric type.I want to find max, min , average values from each cell and save in a different cell arrays of sizes 1x316. This is my code for now:
I have stored cell array in struct s2.This cell array is of sie 1x316.I am trying to return max,min and avg values from a single for loop and saving outputs in 3 different cell arrays.Please help me out on this.
s2 = load('pause_durations_rome.mat');
max_pause_time =cell(size(s2.pause_duration));
min_pause_time = cell(size(s2.pause_duration));
average_pause_time = cell(size(s2.pause_duration));
for iter = 1:length(s2.pause_duration)
a=cell2mat(s2.pause_duration,);
max_pause_time{iter} = max(a(:));
min_pause_time{iter} = min(a(:));
average_pause_time{iter} = mean(a(:));
end

min_pause_time = cellfun( @min, s2.pause_duration);
max_pause_time = cellfun( @max, s2.pause_duration );
average_pause_time = cellfun( @mean, s2.pause_duration );

A non-scalar structure makes this trivial to implement:
S(1).user = 'anna';
S(2).user = 'bob';
S(3).user = 'chen';
...
S(1).data = [0,1,2];
S(2).data = [3,4,5,6];
S(3).data = [7,87,9];
You can add as many users as you need, and any fields that you want. And then accessing the data is very simple:
>> users = {S.user}
users =
'anna' 'bob' 'chen'
>> S(strcmp(users,'bob')).data
ans =
3 4 5 6
You are writing the code and extracting the data, so if you want to make your own life easier then simplify your data organization.
