cell array concept issue

Sir I have an issue on cell array concept.

I want to generate 10 values using a for loop of 10 iteration and in every iteration it will give a single value.

I want to store all values in a single cell one by one value in every iteration.

Is it possible?

If Yes then please give a suggestion.

Hi,

in general no for loop is needed. See the following 2 examples how you could proceed in a simple example:

% 10 random values stored in a
a=randperm(10)

% every value of a in a single cell
b = num2cell(a)
% get the 5th entry of b
content_b_5 = b{5}
% get the whole content of b
content_b_all = cell2mat(b)

% all values of a in one cell as array
c = {a}
% get the 7th entry of c
content_c_7 = c{1}(7)
% get the whole content of c  
content_c_all = c{:}

If you want to proceed in a for loop (which is usually not needed) you could use

% preallocate cell array
d = cell(1,numel(a));
% loop through
for k = 1:numel(a)
    d{k} = a(k);
end
% show d
d

As you can see it is the same result as for creating b, but less efficient and more code to write.

Best regards

right you are - thanks for the hint
