How to store indices of for loop in cell array after satisfying a condition

Hi Mathworkers,

I am having problem in storing indices (That will serve as necessary data in my purpose)of for loops in a cell array after satisfying a condition. Here, there is a draft of the code.

for i=8:110

for j=34:110

for k=95:110

EE=myfunction(i,j,k); %% Function may be any

if EE<=5

(#######)

end

end

end

end

#### at this point, I need the cell array which stores the indices i,j,k for whom the condition (EE<=5) is satisfied.

output may be something like this,

9,50,99

9,61,103

..........

10,34,96

10,35,95 etc..

l=1;
m={};
for......
 if EE<=5
    (#######)   
    m{l}=[i,j,k];
    l=l+1;
 end

Check this way:

>> m={}
m= 
     {}
>> m{1}=[1,2,3];
>> m{2}=[2,2,7];
>> m
m= 
    [1x3 double]    [1x3 double]
>> 

You can acess any cell array, like

>> m{2}
ans =
     2     2     7

One suggestion: If possible reduce the nesting of loops to make the code more efficeint.

Thanks Mr. Kalayan Acharya. Can a called function be used in arrayfun?

Adaroni Saikia deb, you can do that.
