save values in array

I have

A={[1,6,3,2],[3,5,6]};
all_el =[];
for i=1:length(A)
    all_el(end)=A{i}
end

I want to have this result

all_ell=[1,2,3,5,6]

Answer 1

[Bhaskar R]

all_el = unique([A{:}]);

[NA]

if A is

A={{[1,6,3,2]},{[3,5,6]}};
all_el = unique([A{:}]);

I have error

[Bhaskar R]

int_res = cellfun(@(x)[x{:}], A, 'UniformOutput', false);
all_el = unique([int_res{:}]);

Hi there,

It is not pretty clear as what you wanted to do.

To get the desired output, perform the following:

A={[1,6,3,2],[3,5,6]};
% With for loops
all_el =[];
for i=1:length(A)
    all_el=[A{i} all_el];
end
all_el = unique(all_el);

% Without for loops
all_el = unique([all_el{:}])

Hope this helps.

Regards,

Sriram
